Value Collection 01294057 Screw Machine Drill Bit 7.20mm Hss

Product Description

The VALUE COLLECTION 01294057 is a screw machine length drill bit designed for short-reach, high-precision drilling in metal fabrication, maintenance, and production work. Built from high-speed steel (HSS) with an oxide coating for added lubricity and mild corrosion resistance, this bit cuts a 7.20 mm (0.2835 inch) diameter hole with a standard 118-degree point angle. The shortened screw machine length body — 74.00 mm overall — provides greater rigidity and reduced deflection compared to jobber-length bits, making it well suited for drill press and turret lathe work. A two-flute regular spiral design clears chips efficiently through straight-cylindrical shank mounting.

This drill bit is appropriate for general-purpose drilling in steel, cast iron, aluminum, and similar materials where a compact bit length is preferred to minimize runout. Typical applications include production drilling on drill presses, CNC turret lathes, and hand-held power drills in shop environments. Electricians, HVAC techs, and plumbers use screw machine bits when drilling through structural members, panels, or tight cabinet spaces where a standard jobber bit would flex or chatter. The oxide finish suits dry or lightly lubricated cutting conditions.

Key Features

• 7.20 mm (0.2835 inch) diameter for precise hole sizing
• 118-degree standard point angle for general-purpose entry into ferrous and non-ferrous metals
• High-speed steel construction with oxide coating for durability and lubricity
• Screw machine (stub) length body at 74.00 mm OAL for increased rigidity and reduced deflection
• Two-flute regular spiral geometry with web-thinned parallel web for efficient chip evacuation
• Straight-cylindrical shank fits standard three-jaw drill chucks and collet holders

Compatibility

Designed as a general-purpose screw machine length drill bit fitting any three-jaw chuck or collet system accepting a straight-cylindrical shank in the 6.50 mm to 8.00 mm drill bit size range.

Installation Notes

Install in a properly sized drill chuck or collet and tighten securely before operation to prevent slippage. Ensure the workpiece is clamped or fixtured — never hold by hand when drilling metal. Apply cutting fluid or light oil when drilling ferrous materials to extend bit life and improve hole finish. Inspect the cutting edges before each use and replace or resharpen when chipping or dulling is evident.
