Used to countersink holes for the heads of screws in woods, plastic and non-ferrous materials. The 2-flute integral design ensures uniform and concentric results each and every time. Carbide tips provide chip free hole edges and lasts much longer than steel countersinks. Available in a wide variety of sizes, complete with the HSS M2 fully ground drill bit.
Warning: When drilling aluminum/non-ferrous materials, for optimal results and extended tool life use lubricant or air cooling. Make sure the material is fixed and drill is stable during drilling.

Drilling countersinks with these bits on the CNC machine is a great way to save time and have your pieces look great every time
With the adjustable depth drill bit you can adjust them for whatever size material you’re working with. They are best used with a drilling toolpath, utilizing the peck drill option at .25" per pass with a .125" retract height
For best results run at 3,000 RPM with a 30 IPM (Inches Per Minute) plunge rate. No feed rate needs to be set with these as they only move up and down with the Z axis, not side to side. If your software doesn’t allow a 0 feed rate, you can enter 1 IPM (Inch Per Minute) in the feed rate as a placeholder
Application
Natural Woods, Man-Made Boards, MDF, Chipboard, Plywood, Aluminum/Non-Ferrous, Aluminum Composite Material (ACM), Composites, Composite Decking Materials, High Density Polyethylene (HDPE)
