Value Collection 01358431 Screw Machine Drill Bit Size 43

Product Description

The VALUE COLLECTION 01358431 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal, wood, and plastic. It is ground to a wire gauge size 43, with a decimal diameter of 0.0890 inches and an overall length of 1.75 inches, making it well-suited for work in confined spaces where a jobber-length bit would be impractical. The 118-degree standard point angle provides reliable centering on most common materials. The high-speed steel (HSS) construction with an oxide coating offers improved lubricity and corrosion resistance during operation. Installation is performed by machinists, tool-and-die workers, and maintenance technicians.

This screw machine drill bit is used in general-purpose drilling applications requiring a compact, stub-length tool. The shorter overall length reduces flex and deflection, making it appropriate for drill press work, CNC operations, and hand-drill applications where rigidity is critical. The straight cylindrical shank accepts standard three-jaw chucks. With a flute length of 0.75 inches and a regular spiral flute configuration, it provides adequate chip evacuation for shallow-hole drilling tasks common in production and repair environments.

Key Features

• Wire size 43 with 0.0890 inch decimal diameter for close-tolerance work
• 118-degree standard point angle with web-thinned tip for easier penetration and reduced thrust
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Oxide coating improves surface lubricity and provides basic corrosion protection
• Screw machine (stub) length at 1.75 inches OAL reduces deflection in tight clearance applications
• Right-hand cutting with regular spiral flutes for efficient chip removal

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any standard three-jaw drill chuck accepting a straight cylindrical shank in this diameter range.

Installation Notes

This bit should be installed by machinists or qualified maintenance technicians familiar with rotary cutting tools. Secure the straight shank firmly in the chuck before operation and confirm the workpiece is properly clamped to prevent movement. Always operate at the appropriate surface footage for the material being drilled and use cutting fluid where recommended to extend tool life. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
