Value Collection 01188572 No. 57 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188572 is a No. 57 wire gauge jobber-length drill bit ground from high speed steel (HSS) with a black oxide finish. Sized at 0.0430 inches in diameter, it carries a standard 118-degree split-point angle and a regular spiral flute configuration for efficient chip evacuation in general-purpose drilling applications. The web-thinned, tapered web design reduces feed pressure at entry. At 1.75 inches overall length with a 0.75-inch flute length, this is a compact bit suited for precision work in tight clearances. It is installed by machinists, maintenance technicians, metalworkers, and skilled tradespeople who require accurate small-diameter drilling in production or field environments.

This jobber drill bit is designed for use in ferrous metals including steel and cast iron, making it appropriate for light manufacturing, maintenance repair and operations (MRO), and fabrication tasks. The straight cylindrical shank fits standard drill chucks and compatible driver attachments without modification. Its general-purpose grade makes it a reliable choice for repetitive drilling tasks where consistent hole diameter is critical at the No. 57 wire gauge size.

Key Features

• No. 57 wire gauge size — 0.0430-inch diameter for precision small-hole drilling
• 118-degree standard point angle for reliable center-starting on flat and curved surfaces
• High speed steel (HSS) construction provides durability across ferrous workpiece materials
• Black oxide coating reduces friction and provides mild corrosion resistance during use
• Web-thinned tapered web reduces thrust force required at drill entry
• Right-hand cutting, regular spiral flute promotes consistent chip removal
• Straight cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks accepting a 0.0430-inch straight shank, suitable for drilling steel and cast iron workpieces in MRO, fabrication, and light production applications.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with drill press, hand drill, or CNC machine operation. Secure the straight shank fully and evenly in the chuck before operation, and confirm the chuck key is removed prior to starting the machine. Apply appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain hole quality. Inspect the drill point for wear or chipping before each use, as small-diameter bits are susceptible to breakage under lateral load.
