Proto J9634B Brass Drift Punch 3/4 Inch

Product Description

The PROTO J9634B is a brass drift punch designed for aligning holes in metal components during assembly, disassembly, and fabrication work. The 3/4-inch punch tip and 9.5-inch overall length give technicians the reach and control needed for common alignment tasks. Brass construction makes this punch the right choice when working near flammable materials or in environments where spark resistance is required, such as in fuel system service or explosive-atmosphere worksites. Machinists, millwrights, pipefitters, and maintenance technicians keep brass drift punches in their kits for jobs where a steel punch creates unacceptable risk.

This drift punch is suited for use in industrial maintenance, mechanical assembly, and field service applications. It is commonly used to align bolt holes in flanges, structural steel, and machinery frames before fasteners are driven. The 9.5-inch overall length provides adequate offset clearance in confined work areas. At 1.17 pounds, the punch has enough mass for controlled driving while remaining manageable for single-hand use in tight spaces.

Key Features

• Brass construction provides spark-resistant performance in hazardous environments
• 3/4-inch punch size for aligning medium to large bolt holes and component bores
• 9.5-inch overall length offers reach and clearance in confined assemblies
• Soft brass tip reduces damage risk to precision-machined mating surfaces
• Compact 0.8-inch cross-section profile fits tightly grouped fastener patterns

Compatibility

Designed as a general-purpose brass drift punch suitable for hole alignment tasks in mechanical, structural, and industrial assembly applications where spark resistance is required.

Installation Notes

Drift punches are driven with a hammer or mallet — use a ball-peen or dead-blow hammer appropriate to the task, and never strike the punch with a hardened steel hammer head that could chip the softer brass shank. Wear eye protection at all times when driving punches. Ensure the workpiece is properly supported and secured before driving to prevent movement or injury. Remove all pressure, stored energy, or live connections from the assembly before beginning alignment work.
