Value Collection 01350321 Screw Machine Drill Bit 1/2 in

Product Description

The VALUE COLLECTION 01350321 is a screw machine length drill bit designed for general-purpose metal drilling in production and maintenance environments. Built from high-speed steel (HSS) with an oxide finish, the bit measures 1/2 inch in diameter with a 118-degree standard point angle. The shortened overall length of 3.75 inches relative to a jobber-length bit makes it well suited for drilling in confined spaces or on drill presses where rigidity and reduced deflection matter. The web-thinned construction reduces cutting resistance at the tip. Right-hand spiral flutes clear chips efficiently during through-hole and blind-hole operations. Licensed tradespeople and production machinists are the typical end users.

This bit is appropriate for drilling mild steel, cast iron, aluminum, brass, and similar materials in both shop and field settings. Its straight cylindrical shank fits standard three-jaw drill chucks on benchtop drill presses, floor-standing drill presses, and handheld power drills. The screw machine length format is common in fabrication shops, HVAC duct work, plumbing rough-in, and electrical panel work where a shorter, stiffer bit reduces walkout and chatter on metal substrates. The general-purpose grade and oxide coating make it a practical stock bit for everyday trade use rather than a specialty or production-run application.

Key Features

• 1/2 inch diameter with 118-degree standard point angle for general-purpose metal entry
• High-speed steel construction provides toughness across a range of common metals
• Oxide coating reduces friction and provides light corrosion resistance during storage and use
• Screw machine (stub) length at 3.75 inches overall increases rigidity and reduces deflection
• Web-thinned tip lowers thrust requirements and improves penetration on harder stock
• Two regular spiral flutes with straight cylindrical shank for universal chuck compatibility

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in any standard three-jaw drill chuck accepting a 1/2 inch straight cylindrical shank, including benchtop drill presses, floor drill presses, and handheld power drills.

Installation Notes

A licensed machinist, journeyman tradesperson, or qualified technician should secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before beginning the cut. Use cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges for wear or chipping before each use and replace when the point no longer centers cleanly.
