Precision Twist Drill Screw Machine Length HSS Drill Bit Set

Precision Twist Drill screw machine length HSS drill bit sets give machinists, toolmakers and maintenance shops a rigid, short-flute drill for accurate hole making. Screw machine length drills, also called stub length drills, are shorter than jobber length drills. The shorter length gives better rigidity and less deflection, so holes are more accurate and run closer to position, particularly in production and CNC work.

Key Features:

• High speed steel (HSS) construction drills many materials, including steel, stainless steel and aluminum.
• Conventional 118-degree point on the standard HSS line is easy to regrind, so the drills can be reused many times.
• Straight (cylindrical) shank fits standard drill chucks and collets. The drills work in machine and hand-held applications.
• Short, rigid design reduces drill walk and flexing for cleaner, more accurate holes.
• Organized set format keeps the commonly used sizes together for the shop floor, tool crib or service truck.

Precision Twist Drill originally started in the micro drill market, and the brand is now known for a broad line of fractional, number, letter and metric drills. These screw machine length sets suit general machining, fabrication, repair and maintenance work.
