Import 27504 Jobber Length Drill Bit Wire Size 4 Hss

Product Description

The IMPORT 27504 is a jobber-length twist drill bit designed for general-purpose metal drilling across a wide range of trade and shop applications. Built from high speed steel with an oxide coating, this bit measures 3.75 inches in overall length with a 2.5-inch flute length. It cuts a 0.2090-inch diameter hole, corresponding to wire gauge size 4, and features a standard 118-degree split point. Right-hand spiral flutes clear chips efficiently during through-hole and blind-hole drilling. The straight cylindrical shank fits standard drill chucks used by machinists, HVAC technicians, plumbers, electricians, and general maintenance professionals.

This bit is suited for general-purpose drilling in mild steel, aluminum, copper, brass, plastic, and similar materials. The jobber length format is the most common drill-bit format on the job site, balancing reach and rigidity for hand-held drills and drill presses alike. The 0.2090-inch diameter falls within the 0.2000 to 0.2500-inch size range, making it a standard choice for clearance holes, pilot holes, and tap-prep drilling in light fabrication and service work.

Key Features

• Wire gauge size 4, 0.2090-inch cutting diameter for precise hole sizing
• High speed steel construction handles general-purpose metal and non-metal drilling
• Oxide finish provides light corrosion resistance and reduces surface friction during cutting
• 118-degree standard point angle for broad material compatibility
• Web-thinned, tapered web design reduces thrust and improves chip flow
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters
• Right-hand regular spiral flute pattern for conventional forward drilling

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.2090-inch straight cylindrical shank, including hand-held electric drills, cordless drills, and bench-top drill presses.

Installation Notes

Secure the shank fully in the drill chuck before use and verify the chuck is tightened. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Eye protection is required during all drilling operations. Consult applicable shop safety standards and manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
