Value Collection 01291251 Screw Machine Drill Bit 2.20mm Hss

Product Description

The VALUE COLLECTION 01291251 is a screw machine length drill bit designed for close-tolerance drilling in metal, plastic, and composite materials. At 2.20 mm in diameter with a 118-degree standard point angle, this bit delivers precise entry geometry suited for general-purpose drilling tasks. Constructed from high-speed steel (HSS) with an oxide coating, it resists heat buildup and wear under normal shop conditions. The shorter overall length of 40.00 mm (1.5748 inches) provides added rigidity compared to jobber-length bits, making it well-suited for drill press, CNC, and hand-held power tool applications where deflection control matters.

This drill bit is used in light manufacturing, maintenance, and fabrication environments where small-diameter, precision holes are required. The straight cylindrical shank seats securely in standard drill chucks and collet holders. The regular spiral flute geometry evacuates chips efficiently during through-hole and blind-hole drilling. It is a practical choice for machinists, maintenance technicians, and fabricators working with thin-gauge sheet metal, soft alloys, and general-purpose materials in production or repair settings.

Key Features

• 2.20 mm (0.0866 inch) diameter for fine, precise hole sizing
• 118-degree standard point angle for general-purpose drilling on a wide range of materials
• High-speed steel construction provides durability and resistance to elevated cutting temperatures
• Oxide coating reduces friction and extends tool life under standard drilling conditions
• Screw machine length body (40.00 mm overall) adds rigidity and reduces deflection vs. jobber-length bits
• Right-hand cutting, regular spiral flute with web-thinned geometry for improved chip evacuation

Compatibility

Designed as a general-purpose replacement or supplemental bit for standard drill chucks and collet holders accepting straight cylindrical shanks in the 0.00 to 3.50 mm drill bit size range.

Installation Notes

Installation and use of this drill bit should follow standard machining safety practices. Secure the shank fully in the chuck or collet before operation, and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant for the material being drilled where recommended. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the point geometry is compromised to avoid workpiece damage or bit breakage.
