Drill bit model D-60187 belongs to Makita's Imperial HSS-G Black Oxide drill bit range, designed for drilling holes as large as 31/64 inch (12.3 mm)—a size between 7/16 and 1/2 inch—highlighted by its specially designed shank.                                                                                                                Features
Reduced Shank: Allows using a large drill bit (31/64 inch) with a small drill chuck (3/8 inch) easily. 135° Split Point Tip: Enables precise drilling starts, reduces wandering, and reduces the need for a center punch. Fully Ground HSS-G: Exceptional cutting sharpness and uniform geometry provide smooth drilling and excellent chip evacuation. Black Oxide Protection: Black oxide coating resists rust and helps the drill bit withstand high heat and friction.                                                           Application
