Countersinks
Countersinks are required when the head of a bolt or screw needs to be countersunk. They are prefect for deburring and chamfering openings to pre-drilled holes. Atlas Cutting Tools stock a range of countersinks to cater for all needs. Our wide selection of countersinks are built to be used on a variety of different materials. And they will always cut cleanly and accurately. Our products are made to very high standards and are available in high-speed steel (HSS) or with super hard carbide heads. These countersinks are built last and to perform in even the toughest materials.
HSS Countersinks Our High-speed steel countersinks are coated with black oxide to increase corrosion resistance. They are suitable for use on nearly all materials and will create a chatter and burr-free finish.
Solid Carbide Countersinks The solid carbide countersinks provide better rigidity than high-speed steel. It is extremely heat resistant and used for high-speed applications on cast iron, nonferrous materials, plastic and other tough-to-machine materials. The Atlas Cutting Tools’ countersinks are precision manufactured in the USA and are available with same day shipping at affordable prices.
