Product description
【Set Includes】Alphastart premium 4-piece Countersink Drill Bit Set features M2 HSS tapered pilot drill bits in sizes 7/64"×3/8", 1/8"×3/8", 9/64"×3/8", 5/32"×3/8".
【Premium Materials】Constructed with M2 HSS, the pilot drill features a helical chip design for efficient cutting. The sharp HCS edges ensure smooth countersinks and counterbores, making it ideal
for screws conforming to the 82-degree imperial (U.S.) standard.
【Upgraded Aluminum Stop Collar】The upgraded aluminum stop collar comes with built-in bearings that can immediately stop drilling when wood comes into contact. Compared to those traditional stop collars, the wear and tear has been greatly reduced.
【Adjustable Depth】Both drilling and countersinking depths can be easily adjusted using hex screws and depth control stops, providing enhanced flexibility for various tasks and applications.
【Versatile Applications】Suitable for a wide range of materials, including natural wood, engineered wood, MDF, particle boards, plywood, aluminum, non-ferrous metals, and decorative materials, this set is perfect for diverse woodworking and drilling projects.
【Usage Tip】For optimal performance and clean edges, operate the countersinks at a slow speed of approximately 200 RPM.
