Value Collection 01358555 Size 55 Screw Machine Drill Bit Hss

Product Description

The VALUE COLLECTION 01358555 is a screw machine length drill bit designed for short-reach, high-precision drilling in metal and general-purpose materials. Built from high-speed steel (HSS) with an oxide coating for added lubricity and surface hardness, this bit measures 1.625 inches overall length with a 0.625-inch flute length. It cuts a 0.0520-inch diameter hole, corresponding to wire gauge size 55. The 118-degree standard point angle suits flat and slightly curved workpiece surfaces. The straight cylindrical shank fits standard drill chucks. This bit is used by machinists, maintenance techs, and fabricators working with close-tolerance or tight-clearance drilling applications.

The 01358555 is suited for general-purpose drilling in light metals, plastics, and similar materials where a stubby screw machine length profile is preferred over a jobber-length bit. The shortened overall length provides greater rigidity and reduced deflection in drill press and CNC turret setups. Its compact size makes it practical for work in confined spaces or for use in automatic screw machines and repetitive production drilling operations.

Key Features

• Wire gauge size 55, 0.0520-inch decimal diameter for precise small-hole drilling
• HSS construction provides toughness and heat resistance for metal drilling
• Oxide coating reduces friction and helps extend cutting edge life
• 118-degree standard point angle for general-purpose workpiece entry
• Screw machine length (1.625 inches OAL) increases rigidity and reduces deflection
• Right-hand cut, regular spiral flute, straight cylindrical shank for standard chuck compatibility
• Web-thinned parallel web for improved chip evacuation on small-diameter bits

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks, drill presses, CNC turret machines, and automatic screw machines accepting straight cylindrical shanks in the 0.0520-inch diameter range.

Installation Notes

Install and remove drill bits only when the spindle is fully stopped and the machine is powered down or locked out per applicable safety procedures. Secure the straight shank firmly in a properly sized chuck to prevent slippage during cutting. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life and maintain hole quality. Inspect the cutting edges before use and discard any bit showing chipping, burning, or significant wear.
