Amana Tool CNC Solid Carbide 5 Flute Countersink and Chamfer Router Bit, 46468, 90 Degree Angle x 1/2 D x 5mm CH x 1/4 Shank x 1-9/16 Inch Long

This precision countersink drill bit has a 5-flute solid carbide head brazed to a steel shank for reliable performance and long service life. Designed for making accurate 90-degree countersinks, it also functions as a versatile chamfer tool for edges, holes, and contours. Optimized for CNC contour and bore operations, this countersink tool provides the option to use a sufficient lead-in distance. The 46468 model has a fine 3mm tip width, making cuts into the tightest corners and the smallest details achievable. How To Use With A CNC Machine With the adjustable depth drill bit you can adjust for whatever size material you’re working with. They are most effectively used with a drilling toolpath, utilizing the peck drill option at .25" per pass with a .125" retract height. For optimal performance 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. For countersinks with 1/4" round shank, use 1/4" spring collet. For countersinks with 5/16" round shank, use 7-8mm spring collet. For countersinks with 3/8" round shank, use 9-10mm spring collet.
