Proto J9634HB Drift Brass Punch 3/4 Inch 12 in

Product Description

The PROTO J9634HB is a drift punch machined from solid brass, designed for aligning holes in metal components without damaging hardened surfaces or creating spark hazards. At 3/4 inch in diameter and 12 inches in overall length, this punch delivers the reach and mass needed for driving out pins, aligning bolt holes, and seating bearings in tight clearances. Brass construction makes it the correct choice for work near flammable materials or in environments where ferrous tools are restricted. Machinists, millwrights, pipefitters, and maintenance trades reach for brass drift punches when steel would cause galling, sparking, or damage to precision bores.

This punch fits into general maintenance and fabrication work across industrial, commercial, and trade settings. It is commonly used during HVAC equipment installation for aligning heavy component mounting holes, during pump and compressor assembly for seating bearing races, and in pipefitting when aligning large-diameter flanges. The 12-inch length provides clearance when working in recessed assemblies or through structural members where a short punch would not reach.

Key Features

• Brass material prevents sparking, making it suitable for use near flammable gases or liquids
• 3/4 inch punch diameter handles medium-to-large hole alignment tasks
• 12-inch overall length provides reach in deep or recessed work areas
• Non-marring tip protects hardened bores and finished mating surfaces
• Single-piece brass construction resists corrosion and contamination of sensitive assemblies

Compatibility

Designed as a general-purpose drift punch for any application requiring a 3/4 inch brass punch with a 12-inch overall length. Suitable for use in industrial, mechanical, HVAC, plumbing, and pipefitting maintenance tasks where a non-sparking, non-ferrous drift tool is required.

Installation Notes

Use a brass or dead-blow hammer when striking this punch to avoid damaging the struck end or deflecting the punch under load. Always confirm the punch diameter matches the hole or pin being driven before applying force. In spark-restricted or hazardous-atmosphere work areas, follow applicable facility safety protocols and local codes governing non-sparking tool use. Inspect the punch tip and shank for deformation before each use and retire the tool if the tip shows mushrooming or cracking.
