Specification Brand : KEENTECH BulletPoint : Circuit Board Drill Bits BulletPoint1 : 【Premium M2AL High-Speed Steel】- Crafted from M2AL high-speed steel, KEENTECH annular cutters deliver exceptional wear resistance and heat tolerance, ensuring a longer tool life even under heavy-duty use. Built to endure rigorous applications, they provide reliable performance over time. BulletPoint2 : 【Triple-Edge Cutting Technology】- Our 3-edge design evenly distributes the workload across each blade, reducing individual stress while boosting cutting speed, precision, and surface finish. Experience smoother, faster, and more efficient drilling compared to conventional cutters. BulletPoint3 : 【Specifications】KEENTECH annular cutter offers a 5/8 inch cutting diameter and 1 inch cutting depth, and comes with a pilot pin. The 3/4" weldon shank design is compatible with various magnetic drills, including but not limited to Alfra, Evolution, Dewalt, and Hougen. BulletPoint4 : 【Advanced Chip Evacuation System】- The spiral chip chute design enhances chip removal efficiency, reducing friction and heat buildup. This results in: Less cutting force required (even on hard materials); Smoother hole surfaces with minimal burrs; Extended tool life thanks to reduced wear. BulletPoint5 : 【Expert Usage Tips for Optimal Performance】- First, ensure that the two flats of the Weldon shank are aligned with the screws during installation for stable cutting. Second, use the recommended cutting fluid rather than water to extending the tool's life. Third, the right RPM and feed rate can double your efficiency.
