Hss Annular Cutter Set 13Pcs 7/16″-1-1/16″

Features

Annular Cutters cut only the periphery of the hole,ejecting the remaining center as a slug.It produces accurate burr-free holes to close tolerances without pre-drilling or step drilling.

Best used with a drill press or magnetic drilling machine, both for their stability against high torque forces created by such a drill bit and lower RPMs compared to other types of drills. these cutters can be easily used with light duty drilling machines or portable magnetic base drilling machines.

• Time saving: The annular cutters have fewer teeth and less wear, therefore with an annular cutter holes can be made at higher or faster cutting speed and a faster feed rate of the drilling machine.
• Energy savings: Because annular cutters do not have to drill/cut through the complete work piece, they require less thrust and thus less energy to drill through material.
• More finishing: The hole made using an annular cutter is more finished, precise and accurate.
• Easy Using: Due to the unique geometry of the annular cutters, making holes at awkward angles is also very easy.
• Re-sharpening: can be easily re-sharpened on a grinding machine and can be re-used for drilling. Re-grinding can be done until the desired cutting length is available on the annular cutter.
