Import 27423 Jobber Length Drill Bit 7.5 Mm Hss

Product Description

The IMPORT 27423 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Manufactured from high speed steel with an oxide coating for added lubricity and surface protection, it carries a 118-degree standard point angle suited to a wide range of materials. The straight-cylindrical shank seats securely in standard drill chucks. With an overall length of 4.375 inches and a flute length of 3.078 inches, this bit fits the jobber-length profile that machinists, pipefitters, and maintenance technicians reach for daily. Web-thinned geometry reduces entry force and walking on initial contact.

This drill bit is suited to general fabrication, maintenance, and repair work where a 7.5 mm diameter hole is required. Typical applications include drilling clearance holes for fasteners, pipe hangers, electrical conduit supports, and structural attachments. The 0.2953-inch decimal equivalent makes it a direct metric-to-imperial crossover size commonly used in light industrial and mechanical trade work. Right-hand spiral flute design evacuates chips efficiently in through-hole drilling operations.

Key Features

• High speed steel construction with oxide coating for wear resistance and lubricity
• 118-degree standard point angle for versatile multi-material use
• Web-thinned, tapered-web geometry reduces thrust and improves hole entry
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank compatible with standard 3-jaw drill chucks
• Jobber-length profile balances reach and rigidity for general-purpose use

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck or drill press accepting a straight-cylindrical shank in the 0.2953-inch diameter range.

Installation Notes

Secure the shank fully in the drill chuck and confirm concentricity before drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and maintain dimensional accuracy. Always wear eye protection and ensure the workpiece is clamped or fixtured before drilling. Proper drill press speed selection based on material hardness will reduce heat buildup and premature wear.
