Value Collection 01291509 Screw Machine Drill Bit 2.50mm Hss

Product Description

The VALUE COLLECTION 01291509 is a screw machine length drill bit designed for short-reach, high-torque drilling applications in metal and general-purpose materials. Built from high-speed steel (HSS) with an oxide coating for reduced friction and improved chip evacuation, this bit features a 118-degree standard point angle and a right-hand cutting direction with a regular spiral flute. At 2.50 mm diameter and 43.00 mm overall length, it is sized for compact drilling clearances where a jobber-length bit would be impractical. Machinists, tool-and-die tradespeople, and maintenance technicians are the primary users of this format.

Screw machine length drill bits are standard in production machining, CNC drilling operations, and bench work where stub-length tools are required to minimize deflection and improve rigidity. This bit is suited for use in drill presses, CNC machining centers, and hand-held power drills on ferrous and non-ferrous materials. The straight cylindrical shank allows direct mounting in standard chucks. Web-thinned geometry reduces thrust requirements at entry, making it practical for light-duty production runs and repetitive hole operations in steel, aluminum, and similar materials.

Key Features

• 2.50 mm diameter (0.0984 inches decimal equivalent) for precise metric hole sizing
• 118-degree standard point angle for general-purpose entry into common metals
• HSS construction with oxide coating for heat resistance and reduced friction
• Regular spiral flute with web-thinned, parallel web configuration for efficient chip removal
• Straight cylindrical shank for universal chuck compatibility
• Right-hand cutting direction; compatible with standard drill drives

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks accepting straight cylindrical shanks across drill presses, machining centers, and handheld power tools.

Installation Notes

Ensure the drill chuck is fully secured before operation and confirm workpiece is clamped or fixtured to prevent movement during drilling. Power down the machine or disconnect the tool before changing bits. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use; a worn 118-degree point will produce oversized or out-of-round holes.
