We also stock Dowel Pin, Expansion, Taper Shank, Taper Pipe, Taper Pin, Construction, Capscrew, Safety, Bridge and Hand Reamers – all of which are available at affordable prices and with same day shipping. Reamers are primarily used to remove material from, deburr, or enlarge the inside of previously formed holes such as I-Beams, Angles, Channels and Plates. They have cutting flutes on one end and a straight shank on the other. Reamers can either be used with hand or machine tools, such as turret lathes and drill presses used in metalworking. Reamers used with machines are called chucking reamers. They cut on the 45-degree bevel lead; the bevel lead is the angle at the top of the flute. Hand reamers cut both on the bevel lead and the taper lead, which is the full length of the flute. There are also taper pin reamers, which are designed to ream holes for standard taper pins. Taper pin reamers are used with both hand and machine tools. The number of flutes on the reamer determines how fast it can be fed into the hole, how rigid it is, and the space for chips. The more flutes, the more space, feed speed, and rigidity. The type of flute also comes into play. Straight flutes are commonly used, but spiral and helical flutes prevent chip buildup and can be used at higher speeds.
Chucking reamers are most often used in machine shops for close tolerance work. They are designed to remove a minimal amount of stock, usually between 1/64" to 1/32", for a close tolerance hole. Chucking Reamers are available in a variety of different styles such as Straight Flute, Right Hand Spiral, Left Hand Spiral and Intermediate Sizes.
The left hand spiral flute design pushes chips forward out of the hole and allows the reamer to be used in holes that have an interruption. Ground with a starting chamfer to provide easy entry of the reamer in to the hole.
Left Hand Spiral Hand Reamers are designed to enlarge reamed holes by a few thousandths. Left hand spiral is for reaming keyways and interrupted cut holes. The pilot and guide on these reamers are ground slightly undersize for clearance and to guide reamer. The flutes also have a ground starting taper to help guide reamer into hole.
All of our HSS (High Speed Steel) Taper Reamers are designed for reaming holes so that standard taper pins can fit properly. The results will be attained if the hole is drilled a few thousandths smaller than the small diameter of the finished reamed hole.
All of our HSS (High Speed Steel) Dowel Pin Reamers are manufactured with a minus tolerance, used for reaming holes for dowel pins in the automotive industry and mold shops.
Expansion reamers are precision tools that can be reused multiple times and are generally used for reaming abrasive material. They are built with slots cut between the flutes and a tapered screw in the head. As the reamer is used and the cutting edges are worn down, the user simply turns the screw to expand the reamer, re-clears it, sharpens it back to its original size and goes right back to work. Expansion reamers are handy tools that allow the user to keep working with the same reamer multiple times, without having to buy a new reamer.
Our HSS (High Speed Steel) Cap Screw Counterbores are designed to create a recess for socket head cap screws and shoulder screws.
Our HSS (High Speed Steel) Safety Reamers are especially adapted for heavy duty reaming as encountered in structural steel assembly fabrication. They are tapered at the point which allows you to enter holes that are out of alignment.
Our HSS (High Speed Steel) Bridge Reamers are commonly used for bridgework, ship construction and structural steel fabrication where diameter accuracy is important. Bridge Reamers have pilot type points for the best alignment possible and allows easy entry into small, off-center holes.
Our HSS (High Speed Steel) Taper Shank Bridge Reamers are designed for use in structural steel fabrication bridge work and ship construction to line up bolt and rivet holes. They can be used in portable electric or pneumatic equipment. These tools are also referred to as Boilermaker’s Reamers, Rivet Hole Reamers, Aligning Reamers, or Construction Taper Reamers.
Our HSS (High Speed Steel) Construction reamers are generally used to create bolt clearance holes when fastening steel beams, truck chassis etc.
Our HSS (High Speed Steel) Taper Pipe Reamers are designed for use in easy to ream materials. They are used prior to tapping dry seal and ANPT threads when high quality threads are required.
Atlas Cutting Tools stock an extensive range of over 15,000 Standard, Carbide, Cobalt and High Speed End Mills all USA manufactured to the highest standard. Our End Mills are all available with same day shipping at affordable prices. An End Mill is a type of milling cutter designed to be held by the shank on one end in order for it to cut with the opposite end. The advantage to an End Mill is that, unlike any other type of milling cutter, it is capable of cutting on the periphery, the face or the end of the cutter. At Atlas, our offering of End Mills is extensive-ranging from conventional HSS, Cobalt, and Solid Carbide Roughing & Finishing Mills to application and material specific tools employing the latest geometries and coating technologies all resulting in improved efficiency and productivity for you. The number of flutes can range from two to eight. The fewer flutes offer the most efficient chip removal, but a higher amount of flutes provide a smoother finish. The End Mill’s helix angle is also important. Most general purpose End Mills have a 30-degree helix angle because it is halfway between “slow” (low-angle) and “fast” (high-angle) helix End Mills. Specific projects require special styles of End Mills. Ball Nose End Mills are best for machining round bottom holes and complex contoured surfaces. Square Nose End Mills have square ends and are best for slotting, profiling, and roughing. Corner Radius End Mills have a square end with rounded corners on the cutting edges to reduce chipping. Double-ended End Mills have the same cutting edges and styles on both ends, doubling the tool’s life compared to Single-ended End Mills. Cutter material is an important consideration when selecting an end mill. Carbide End Mills can run at higher speeds than high-speed or cobalt steel, it is also more resistant to wear and can be used at high cutting temperatures. Cobalt Steel End Mills resists abrasion and high cutting temperatures, and has higher feed rates than High-speed Steel. High-speed Steel End Mills are compatible with a variety of materials and is typically used for less demanding jobs. An End Mill’s end cut type can either be center cutting or non-center cutting. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. All Carbide End Mills are center cutting. Non-center-cutting End Mills are suitable for peripheral milling and finishing, but cannot be used to make plunge cuts. HSS and Cobalt End Mills will specify if they are center or non-center cutting. Atlas Cutting Tools end mills offer a variety of coatings. Some end mills are uncoated, while others are coated with finishes to enhance performance. Most finishes extend the life of the End Mill and allow higher cutting speeds and feed rates. Atlas Cutting Tools End Mill Coatings: TiN (Titanium Nitride) End Mill Coating A special multilayer coating for edge retention and corrosion resistance when used on a wide range of materials including iron based, hardened steels, and stainless steels. Typically TiN is used in applications with lower cutting speeds than TiCN and ALTiN but often improves the tool's lifetime by a factor of three or more. TiCN (Titanium Carbonitride) End Mill Coating A general purpose coating that offers improved wear resistance to abrasive, adhesive, or difficult to machine materials such as cast iron, aluminum alloys, steels, copper and more. This is a common used substitute when the advantages of ALTiN cannot be used, as in applications that cannot generate the speeds and feeds required for higher cutting temperatures. TiCN is harder and more impact resistant than TiN and can improve tool life by as much as 800%. ALTiN (Aluminum Titanium Nitride) End Mill Coating This is a high performance coating for milling, tapping and drilling in stainless steels, carbon steels, alloy steels, and cast iron. This coating is extremely heat resistant and can be used with or without coolant. It is exceptional in difficult to machine materials where adhesive wear is particularly high and can be run at much higher speeds and feeds than all other coatings.
When it comes to drilling, there are many different types of drill bits available on the market, each designed to suit specific applications and materials.
Carbide Drills: Carbide drills are made from tungsten carbide, a very hard and durable material that can withstand high-speed drilling and maintain its sharpness for longer periods. They are ideal for drilling through harder materials such as composites, ceramics, and hardened steel. Atlas Cutting Tools carries the largest selection of solid Carbide Drills in a range of sizes, shapes and styles that are manufactured in the USA using the preeminent sub micro-grain carbide materials so as to provide utmost efficiency and performance. As compared to other elements, Carbide has higher levels of resistance to heat, wear and tear along with having a long working life. With that said, it is no wonder that carbide drill bits offered by us provide outstanding drilling solution for high production applications. Carbide drills provide faster cutting rates, extensive tool life and unmatched dimensional and positional precision and improved finish to the surface. Tighter tolerances and shorter cycle times of carbide drills ensures maximum utilization of the machineries and better quality of the parts while reducing the operational costs.
Cobalt Drills: Cobalt drills are made from high-speed steel alloy enriched with cobalt, which makes them tough and resistant to heat. They are ideal for drilling through tough and hard materials such as stainless steel, cast iron, and titanium. Cobalt drills are also more affordable than carbide drills, making them a good choice for general-purpose drilling applications where high precision and speed are not required.
HSS Drills: HSS drills (high-speed steel) are made from a steel alloy containing high amounts of tungsten, chromium, and vanadium. They are a versatile and durable option for drilling through materials such as wood, plastic, and soft metals. HSS drills are typically less expensive than carbide and cobalt drills, making them a popular choice for DIY and hobbyist projects.
Silver and Deming Drills: Silver and Deming drills are large diameter drills that feature a reduced shank diameter, making them compatible with standard drill chucks. They are often used in industrial applications that require large-diameter holes in materials such as steel, aluminum, and wood. Silver and Deming drills are available in both cobalt and HSS materials.
Choosing the right drill bit depends on the specific application and material being drilled. Carbide drills are ideal for precision drilling in harder materials, cobalt drills are suitable for drilling through tough and hard materials, HSS drills are versatile and affordable, and Silver and Deming drills are used for larger diameter holes in various materials. Understanding the advantages and applications of each drill bit type can help ensure the best results for your drilling project.
