Value Collection 01296458 Screw Machine Drill Bit Hss

Product Description

The VALUE COLLECTION 01296458 is a screw machine length (stub length) twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide finish, it resists heat buildup and light corrosion during repeated use. The bit measures 0.5709 inches in diameter — equivalent to 14.50 mm — and features a 118-degree point angle with a standard point and web-thinned tip that reduces thrust and improves center starting. Its shorter overall body compared to a jobber-length bit provides added rigidity in drill press and CNC turret applications, reducing deflection and chatter on production runs.

This drill bit is suited for machine shop, maintenance, and light production work. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. The regular-spiral, spiral-flute geometry evacuates chips efficiently in both through-hole and blind-hole drilling. The right-hand cutting direction is standard for use with conventional clockwise-rotating spindles on drill presses, lathes, milling machines, and hand drills. No coolant-through capability is present, so cutting fluid should be applied externally when drilling harder materials or at elevated feeds.

Key Features

• 0.5709 inch (14.50 mm) diameter for precise hole sizing within the 0.5000 to 0.6000 inch range
• High speed steel construction handles moderate heat and wear across a wide range of workpiece materials
• Oxide finish provides light lubricity and corrosion resistance during storage and use
• 118-degree standard point angle with web-thinned tip reduces walking and entry thrust
• Screw machine (stub) length body increases rigidity and reduces deflection versus jobber-length bits
• Straight-cylindrical shank fits standard drill chucks and quick-change toolholders without modification

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in drill presses, CNC turret drilling machines, lathes, and hand-held drills accepting a straight-cylindrical shank in the 0.5000 to 0.6000 inch diameter range.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before beginning a cut. Always bring the spindle to a full stop before changing or inspecting the bit. Apply cutting fluid externally when drilling ferrous metals or harder alloys to extend tool life and improve hole finish. Ensure the workpiece is clamped firmly — a bit of this diameter generates significant torque and can cause workpiece rotation if unsecured.
