Worth it for contractors who need reliable cold chisels for cutting rivets, shaping metal, and general demolition work. The heat-treated alloy steel construction saves money over time, and the kit handles everything from cutting rivets and rods to forming and shaping steel, brass, bronze, cast iron, and aluminum. At 4.4 stars across 114 reviews, it delivers what Mayhew promises.
Skip it if you’re buying for masonry work. These chisels aren’t intended for use on masonry materials — they’re designed specifically for metals softer than the cutting edge.
Heat-Treated Steel Built for Montana Work
The construction tells the story. Every chisel starts as heat-treated alloy steel, forged and heat-treated for strength, then finished with a shot blast surface. That shot blast finish isn’t just cosmetic — it provides better grip when your hands are covered in oil or cutting fluid.
The Parker-type tapered shafts matter more than most contractors realize. That taper prevents mushrooming at the strike end, which means fewer flying metal fragments when you’re hammering away at a seized bolt in some equipment shed.

Three Sizes That Cover the Bases
The 89062 set includes three essential sizes:
| Model Number | Size | Length |
|---|---|---|
| 10302 | 3/8 inch | 5 inches |
| 10402 | 1/2 inch | 6 inches |
| 10502 | 5/8 inch | 6-1/2 inches |
The 3/8” handles precision work — splitting seized nuts, starting cuts in tight spaces. The 1/2” does most of your daily cutting and shaping. The 5/8” tackles heavier demolition where you need more mass behind each strike.
What’s smart about this size range is the length progression. That extra half-inch on the largest chisel gives you better leverage and keeps your knuckles further from the workpiece when swinging a heavier hammer.
Material Compatibility Worth Memorizing
These chisels work on steel, brass, bronze, cast iron, aluminum, and copper. That covers 90% of what you’ll encounter in Montana metalwork — from irrigation equipment to stock trailers.
They won’t work on concrete, stone, masonry, or metals harder than the chisel edge. Trying to cut hardened bolts or spring steel will just chip the edge. Know your limits and these chisels will last decades.
What 114 Contractors Say
Across Home Depot (4.4 stars, 114 reviews), Northern Tool (4.3 stars, 72 reviews), and McCoy’s Building Supply (4.8 stars, 4 reviews), the pattern stays consistent. Contractors praise the durability, edge retention, value, and sturdy build.
The main complaints center on basic finish compared to premium sets. Fair enough — you’re not getting mirror-polished chrome here. You’re getting working tools.
The lifetime warranty covers manufacturer defects. That’s standard for quality USA-made hand tools, but it still matters when you’re trusting these chisels to perform in sub-zero equipment repairs or summer fence demolition.
Frequently Asked Questions
Q: Can these cold chisels cut through rebar?
These chisels are designed for metals softer than the cutting edge. Standard rebar is typically mild steel, which these can handle. However, epoxy-coated or high-strength rebar may damage the cutting edge. The chisels work best on steel, brass, bronze, cast iron, aluminum, and copper.
Q: What’s the difference between Mayhew’s Select and Pro series?
The 89062 belongs to the ‘Select’ series, which is the standard retail line. The ‘Pro’ series often features advanced handles (like in pry bars) or different material finishes. For cold chisels, the Select series delivers professional-grade performance.
Q: Do I need to sharpen these before first use?
The shot blast finish and heat treatment mean these arrive ready to work. When they eventually dull, regrind to the original factory angle and avoid overheating the tip during grinding to preserve the temper.
Q: How do these compare to Harbor Freight’s Icon chisels?
Market alternatives include Tekton, Icon (Harbor Freight), Proto, Stanley, and Snap-on. Without side-by-side testing data, the main differentiator remains Mayhew’s USA manufacturing and lifetime warranty coverage.
