Value Collection 0572761 Screw Machine Drill Bit

Product Description

The VALUE COLLECTION 0572761 is a screw machine length (stub) drill bit engineered for high-speed drilling in metal and hard materials. Built from cobalt high-speed steel, it delivers improved heat resistance and wear life compared to standard HSS tooling. The 135-degree split point geometry reduces walking and allows drilling to start without a center punch. The straw-colored finish indicates a controlled heat treatment process applied during manufacturing. This bit is a right-hand cut, two-flute design with a straight shank and regular spiral flute configuration. It is used primarily by machinists, maintenance techs, and metalworking professionals in production and repair environments.

Screw machine length drill bits are shorter than jobber-length bits, providing greater rigidity and reduced deflection when drilling in a drill press, turret lathe, or CNC machining center. The stub length is well-suited for applications where limited axial clearance is a factor or where chatter and bit flex must be minimized. The cobalt construction makes this bit appropriate for stainless steel, cast iron, hardened alloys, and other materials that generate significant heat at the cutting edge.

Key Features

• Cobalt high-speed steel construction for superior heat and wear resistance
• 135-degree split point reduces thrust force and eliminates center-punch requirement
• Stub (screw machine) length provides added rigidity and reduced deflection
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Straight shank compatible with standard drill chucks and collet holders
• Straw finish indicates heat-treated surface for extended tool life

Compatibility

Designed as an OEM-style replacement or standard shop-stock drill bit for use in drill presses, turret lathes, CNC machining centers, and hand-held drilling equipment accepting a straight-shank bit.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or trained trade professional. Secure the straight shank fully in the chuck or collet before beginning any drilling operation and confirm the workpiece is properly clamped. Operate at the appropriate cutting speed and feed rate for the material being drilled. Do not force the bit or run it dry in materials that require cutting fluid, as this will accelerate edge wear on cobalt tooling.
