Proto J9638B Brass Drift Punch 3/8 Inch 6 Inch Oal

Product Description

The PROTO J9638B is a brass drift punch designed for driving pins, aligning holes, and removing bearings, pins, and fasteners without damaging surrounding ferrous components. At 3/8 inch tip diameter and 6 inches overall length, it fits comfortably in confined work areas common in mechanical, HVAC, and electrical panel service. Brass construction makes it the correct choice when working near flammable materials or in environments requiring non-sparking tools. Machinists, millwrights, electricians, and field technicians reach for brass drift punches when steel contact with the workpiece is not acceptable.

This punch is suited for light to medium pin-driving tasks in residential and commercial service environments. Typical applications include aligning bolt holes during equipment mounting, driving roll pins in fan assemblies, and removing tapered pins from motor shafts. The 6-inch length provides enough reach for recessed fasteners while keeping the tool manageable for single-hand use. The 0.21-pound weight keeps fatigue low during repetitive work.

Key Features

• Brass construction — non-sparking, safe near flammable materials or in explosive atmospheres
• 3/8 inch punch tip diameter for standard pin and drift applications
• 6 inches overall length for reach into recessed areas without sacrificing control
• Lightweight at 0.21 pounds — reduces hand fatigue during repetitive strikes
• Compact cross-section (0.4 inches height x 0.4 inches width) fits tight clearances

Compatibility

Designed as a general-purpose brass drift punch suitable for pin-driving and hole-alignment tasks across mechanical, HVAC, plumbing, and electrical service applications where a 3/8 inch drift punch is required.

Installation Notes

Brass drift punches are installed by hand with a hammer or mallet — use a ball-peen or brass-faced hammer for best results and to avoid mushrooming the punch head. Always wear eye protection when driving punches. Do not use this tool to drive hardened steel pins or fasteners, as brass is softer than steel and the tip will deform under excessive impact force. Inspect the punch head before each use and dress any mushrooming with a file to prevent metal fragment hazards.
