Built from high speed steel with an oxide finish, the set covers sizes from 1\/16 inch to 3\/8 inch in 1\/64-inch step increments. Each bit features a 135-degree split-point tip that reduces walking on contact and requires no center punch on most surfaces. Right-hand cutting geometry pairs with the straight shank design for use in standard drill chucks. This set is installed and used by machinists, HVAC technicians, plumbers, electricians, and general trade professionals who need consistent, repeatable hole quality in metal stock.\u003c\/p\u003e\u003cp\u003eThis set is suited for residential and commercial trade work involving metalworking and multipurpose drilling tasks. The screw machine length configuration offers a shorter, more rigid body than jobber-length bits, which improves hole accuracy in tight spaces such as sheet metal enclosures, electrical panels, pipe hangers, and structural brackets. The 1\/64-inch size graduation makes it practical for a wide range of pilot, clearance, and finish hole requirements. The 21 bits store in an included metal or plastic case for jobsite organization.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21-piece set covering 1\/16 inch to 3\/8 inch in 1\/64-inch increments\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip reduces bit walking and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, straight shank — fits standard 3-jaw drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 specification designation for quality and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eIncludes metal or plastic storage case for organized transport and access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks on benchtop drill presses, hand drills, and magnetic base drills used in metalworking and general trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eScrew machine drill bits are installed and used by trade professionals working with metal substrates.
