Value Collection 01294453 Screw Machine Drill Bit 8mm Hss

Product Description

The VALUE COLLECTION 01294453 is a screw machine length drill bit designed for general-purpose drilling in metal, plastic, and other common materials. It measures 8.00 mm (0.3150 inches) in diameter with an overall length of 79.00 mm (3.11 inches). The bit is ground from high-speed steel (HSS) with an oxide coating to reduce friction and extend tool life. The 118-degree standard point angle is well-suited for drilling into a wide range of workpiece materials without the need for center-punching on flat surfaces. A web-thinned construction reduces thrust load at the tip, making it easier to start and drive the bit through material efficiently.

Screw machine length drill bits are shorter than jobber-length bits, providing added rigidity and reduced deflection in tight spaces or on drill presses, milling machines, and CNC machining centers. This bit is appropriate for production and maintenance environments where accuracy and repeatability matter. The right-hand cutting direction and regular spiral flute geometry handle chip evacuation in standard drilling operations. Trades and maintenance personnel working on HVAC equipment, panel fabrication, pipe fitting, and mechanical assemblies commonly use screw machine bits for precision hole placement in confined clearances.

Key Features

• 8.00 mm diameter with 118-degree standard point angle for general-purpose drilling
• High-speed steel construction with oxide coating for reduced friction and improved durability
• Screw machine (stub) length at 79.00 mm overall for increased rigidity and reduced deflection
• Right-hand cutting direction with regular spiral flute for efficient chip removal
• Web-thinned tip reduces required thrust force during drilling
• Straight cylindrical shank fits standard drill chucks and collets

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks, collets, and tool holders accepting an 8.00 mm straight cylindrical shank across bench drill presses, milling machines, and hand drills.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and trade professionals using standard drilling equipment. Secure the straight shank firmly in a properly sized chuck or collet before operation. Always power down and lock out the machine before changing bits. Use appropriate cutting fluid or lubrication when drilling ferrous metals to preserve cutting edge life and maintain dimensional accuracy.
