Import 27556 Jobber Length Drill Bit Wire Size 56 Hss

Product Description

The IMPORT 27556 is a jobber-length twist drill bit sized to wire gauge 56, equivalent to 0.0465 inches in decimal. It is manufactured from high speed steel with an oxide coating that provides basic lubricity and surface protection during drilling operations. The 118-degree standard point angle suits general-purpose work in soft to medium-hardness materials. At 1.75 inches overall length with a 0.75-inch flute, this bit is well-suited to benchtop drill presses, hand drills, and CNC drill applications where small-diameter precision holes are required. Licensed tradespeople in electrical, HVAC, and plumbing work commonly use wire-gauge bits for pilot holes, sheet metal, and light-gauge tubing.

This bit is appropriate for general-purpose drilling in metalworking, sheet metal fabrication, electrical panel work, and mechanical assembly. The straight-cylindrical shank fits standard three-jaw chucks found on drill presses and hand drills. The right-hand spiral flute clears chips efficiently in typical production and service environments. Web-thinned geometry at the tip reduces entry force, which is beneficial when working in thin or brittle materials.

Key Features

• Wire gauge size 56, 0.0465 inches decimal diameter
• 118-degree standard point angle for general-purpose drilling
• High speed steel construction with oxide finish coating
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Web-thinned, tapered web configuration reduces drill entry force
• Straight-cylindrical shank compatible with standard three-jaw chucks

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard three-jaw chuck accepting a 0.0465-inch straight-cylindrical shank, including hand drills, benchtop drill presses, and CNC drilling equipment.

Installation Notes

This bit is installed and operated by machinists, electricians, HVAC technicians, and plumbers performing pilot or through-hole drilling tasks. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when drilling metal to extend bit life. Replace the bit at the first sign of tip dulling to avoid workpiece damage or bit breakage at this small diameter.
