7″ .401″ Air Hammer Drift Punch Set Jitterbug 3/16″-1/2″

Description

Product Overview

The Jitterbug 7″ .401″ Air Hammer Drift Punch Set is engineered for demanding automotive and industrial applications where reach and strength are essential. Each punch features a hardened steel tip with a precision‑ground .401″ shank that mates seamlessly with most standard air hammers, ensuring a secure fit and consistent power transfer. The set includes five sizes—3/16″ (5.2 mm), 1/4″ (6.5 mm), 5/16″ (7.7 mm), 3/8″ (9.3 mm), and 1/2″ (12.7 mm)—providing versatile coverage for a wide range of bolt and pin diameters. The 7″ (177 mm) extra‑long parallel shaft is designed to stay clear of the workpiece, reducing the risk of the tool becoming lodged in tight cavities. Constructed from high‑grade alloy steel, the punches resist wear, deformation, and cracking even under repeated high‑impact cycles. At a lightweight 1.75 lb, the set balances durability with ease of handling, allowing technicians to work for extended periods without fatigue. Package dimensions of 8 × 4.13 × 2.75 in keep storage simple and protect the components during transport.

Usage

This drift punch set excels in environments where corrosion, rust, or seized fasteners impede disassembly. Automotive mechanics will find it indispensable for extracting stubborn bolts, removing seized pins, and aligning dowels during engine rebuilds or chassis repairs. In the aerospace sector, the long reach and precise sizing help technicians free locked components without damaging surrounding structures. Maintenance professionals in heavy‑equipment facilities rely on the set to quickly free jammed pins on hydraulic cylinders, gearboxes, and conveyor systems. The robust shank and hardened tips also make the set suitable for metalworking shops where precision alignment of holes is required before welding or machining operations. Because the punches are compatible with standard air hammers, users can integrate them into existing tool inventories without additional adapters, streamlining workflow and reducing downtime. Whether you are a seasoned professional or a dedicated DIY hobbyist, the set’s ergonomic design and balanced weight enable accurate force application in cramped or awkward positions.

FAQ

What air hammers are compatible with this set?

The .401″ shank is a common standard for most pneumatic air hammers, including models from major brands such as Ingersoll, Chicago Pneumatic, and Makita. As long as the tool accepts a .401″ shank, the punches will fit securely.

Can the punches be used on materials other than steel?

Yes, the hardened tips are suitable for aluminum, brass, and other non‑ferrous metals. However, for extremely hard alloys or hardened steel fasteners, a higher‑impact air hammer may be required to achieve optimal results.

Is there a warranty on this product?

Jitterbug offers a limited one‑year warranty covering manufacturing defects. If a punch shows signs of premature wear or damage under normal use, contact customer service for a replacement.

How should I maintain the punches for long‑term durability?

After each use, wipe the punches clean to remove oil, debris, and moisture. Store them in a dry environment and avoid exposing them to corrosive chemicals. Periodic inspection for chipping or wear will help maintain performance.

What is the best way to remove a seized bolt with this set?

Start with the smallest size that fits the bolt head, apply short, controlled bursts of air hammer impact, and gradually work up to larger sizes if needed. The extra‑long shaft helps keep the tool aligned while delivering consistent force.
