Experience precision and efficiency with the Amana Tool Countersink Bit including a High-Speed-Steel (HSS) M2 fully ground drill bit. This countersink drill bit set for wood, composite, and aluminum is designed for long-lasting performance. This tool is designed to minimize chatter, reduce heat, and produce clean, precise holes in a variety of materials. Available in multiple sizes, the Carbide Tipped Countersink delivers dependable performance for professionals who demand precision and reliability. 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. Please note: When drilling aluminum-ferrous materials, for optimal performance and extended tool life use lubricant or air cooling. Make sure the material is fixed and the drill is stable during drilling.
