AMGSH 150mm Air Hammer Kit — 4500 BPM Pneumatic Hammer with 4 Hardened Chisels, Quick-Change Retainer

The AMGSH 150mm Air Hammer Kit is a high-impact pneumatic hammer delivering up to 4500 BPM with a 150mm stroke and four hardened chisels for cutting, chiseling, and scraping tasks.

Designed for mechanics, metalworkers, and serious DIYers, this air hammer combines an extended 150mm (5.9") piston stroke with robust construction to increase impact force for demanding jobs. The kit includes four purpose-made chisels and a quick-change retainer, so you can move between muffler removal, panel work, and spot weld breaking without fumbling for tools. Built from aluminum alloy with heat-treated bits, it balances power and durability for workshop environments.

How much power and stroke does this air hammer provide?

The AMGSH air hammer produces up to 4500 blows per minute and features a long 150mm piston stroke for deeper, more forceful impacts. That extended travel multiplies the tool's per-stroke energy, making it better suited to cutting and heavy-duty chiseling than shorter-stroke models.

• Maximum 4500 BPM for rapid impact work
• 150mm (5.9") long piston stroke for increased impact force
• Consistent performance under continuous use with proper air supply

What chisels and attachments are included, and how do they fit?

The kit ships with four hardened chisels: a 4.93" x 1/8" taper punch plus three 4.9" x 0.78" bits (panel cutter, flat chisel, and spot weld chisel). A quick-change spring retainer and a fitting for a 1/4" hose ensure fast swaps and a secure connection to standard air lines.

• 4.93" taper punch for punches and alignments
• Panel cutter for bodywork and sheet metal separation
• Flat chisel for scraping and general demolition
• Spot weld chisel for breaking welds cleanly without extra heat
• Quick-change retainer and 1/4" hose fitting for fast accessory changes

How rugged is the construction and what maintenance does it need?

The main housing is aluminum alloy to resist shop wear while keeping weight manageable, and the chisels are heat-treated for longer edge life. Regular lubrication of the air inlet and occasional inspection of the retainer and bits will keep the hammer performing reliably under heavy use.

• Aluminum alloy body for durability and lighter weight
• Heat-treated chisels for long service life and edge retention
• Recommended: oil inlet before use and tighten retainer weekly

What tasks is this air hammer best suited for in a workshop?

This tool excels where high-impact, repetitive blows are needed: auto body panel removal, muffler and exhaust work, spot weld separation, and metal scraping. Its long stroke and specialized chisels make it more effective for thicker materials and stubborn fasteners than smaller units.

• Muffler and exhaust disassembly
• Cutting and separating body panels and sheet metal
• Breaking spot welds and removing rusted seams
• Scraping and chiseling tasks in fabrication and repair

Who is this for: The AMGSH 150mm Air Hammer Kit is aimed at professional mechanics, metalworkers, and dedicated hobbyists who need a reliable, high-impact pneumatic tool. If you regularly confront thick sheet metal, welded joints, or rusted components and use an air compressor rated to support pneumatic hammers, this kit provides the chisels, quick-change hardware, and stroke length to finish tougher jobs faster and with less fatigue than shorter-stroke models.
