Malco makes sheet metal tools for HVAC contractors, roofers, and anyone else who cuts, bends, or shapes metal for a living. They’ve built a reputation as a manufacturer of high-quality, innovative hand tools used by professionals in HVAC, exterior remodeling, and fence and rail installation.
The brand focuses on three things that matter: tools that save time, reduce hand fatigue, and don’t damage expensive materials. Their TurboShear attachments turn any drill into a power shear. Their seamers deliver 7:1 leverage for bending thick metal without killing your hands. Their aluminum snips weigh a third less than steel versions while cutting the same materials.
TurboShear Attachments Save Real Time
The HD TurboShear cuts 18-gauge mild steel, 20-gauge spiral duct, and 14-gauge aluminum. That covers 90% of what Montana contractors encounter on commercial jobs. The head rotates 360 degrees, which matters when you’re cutting ductwork in a cramped mechanical room or trimming metal roofing at the ridge.
| HD TurboShear Cutting Capacities | Thickness |
|---|---|
| Spiral Duct | 20 gauge (0.040”) |
| Galvanized Steel | 18 gauge (0.052”) |
| Mild Steel | 18 gauge (0.048”) |
| Stainless Steel (non-hardened) | 20 gauge (0.032”) |
| Aluminum | 14 gauge (0.060”) |
| Copper | 0.100” |
The standard TS1 model handles 20-gauge galvanized steel with 1/2” starter hole capability for blind cuts. Both models work with any 14.4V or higher drill — cordless or corded. The aluminum-cast shear head keeps weight down while the hardened carbon steel blades handle thousands of cuts.
These aren’t homeowner toys. The lateral blade adjustment compensates for wear, extending blade life significantly. When blades finally do wear out, they’re replaceable — you’re not throwing away the whole tool.
Seamers That Deliver 7:1 Leverage
Malco’s 9-inch seamer provides 7:1 mechanical advantage with 2-inch max bend depth marked in 1/4-inch graduations. That leverage ratio transforms a 20-pound grip into 140 pounds of bending force. Critical when you’re bending dozens of drip edges in January and the metal’s cold and stiff.
| 9-inch Seamer Specifications | Value |
|---|---|
| Jaw Width | 9 inches |
| Max Bend Depth | 2 inches |
| Depth Graduations | 1/4 inch increments |
| Leverage Ratio | 7:1 mechanical advantage |
| Weight | ~2.5 lbs |
The die-cast zinc jaws with nickel plating protect painted metal surfaces from marring. That matters on pre-painted standing seam panels where every scratch shows. The slightly bowed jaws ensure even pressure across the full 9-inch width — no wavy bends or uneven hems.
The RedLine grip handles reduce hand fatigue during repetitive bending. After forming 200 feet of drip edge, the difference between cushioned grips and bare metal handles becomes crystal clear.
Aluminum Snips Cut Weight Without Sacrificing Performance
Malco’s 14-inch aluminum snips weigh just 20 ounces — about 1/3 lighter than comparable steel snips. Less weight means less fatigue during extended cutting sessions. The 3.25-inch cutting length per stroke means fewer cuts to complete the job.
| 14-inch Aluminum Snip Cutting Capacity | Thickness |
|---|---|
| Vinyl Siding | 0.055” |
| Aluminum | 0.035” |
| Copper | 0.023” |
| Stainless Steel | 26 gauge (0.018”) |
| Galvanized Steel | 24 gauge (0.028”) |
| Mild Steel | 24 gauge (0.024”) |
The aluminum handles aren’t just about weight reduction. The larger handle loops accommodate gloved hands — essential when working in Montana winters. The sleek head design navigates tight spots better than bulky aviation snips.
Field-replaceable blades extend tool life. When cutting edges dull, swap the blades instead of buying new snips. The pressure-fit design means no special tools required for blade replacement.
Who Makes Malco and Why It Matters
Malco was founded in 1950 and produces their tools in Annandale, Minnesota. They’re employee-owned, which typically translates to better quality control — the people building the tools have skin in the game.
The company won Manufacturing Excellence Awards from Twin Cities Business in 2022 and was named 2024 Medium Manufacturer of the Year by the Minneapolis/St. Paul Business Journal. More importantly for contractors, they back their tools with a lifetime warranty.
The Bottom Line on Malco
Malco tools cost more than imports. They also cut cleaner, bend straighter, and last longer. The TurboShear attachments pay for themselves in labor savings within a few jobs. The 7:1 leverage on their seamers means your crew can work longer without hand fatigue. The lightweight aluminum snips reduce arm strain on repetitive cuts.
For Montana contractors dealing with cold-stiffened metal, painted panels that can’t be scratched, and job sites where the nearest tool store is an hour away, Malco’s focus on durability and performance makes sense. Buy the tools that’ll still be working when your apprentices become journeymen.
Frequently Asked Questions
Q: What materials can Malco TurboShear attachments cut through?
Malco’s HD TurboShear cuts 18-gauge galvanized steel, 18-gauge mild steel, 20-gauge stainless steel (non-hardened), 14-gauge aluminum, and copper up to 0.100 inches thick. The standard TS1 model handles 20-gauge galvanized steel, 18-gauge mild steel, and 16-gauge aluminum.
Q: How much leverage do Malco seamers provide for bending metal?
Malco’s 9-inch seamer provides a 7:1 mechanical advantage, meaning a 20-pound grip force translates to 140 pounds of bending force. The seamer handles bends up to 2 inches deep with 1/4-inch graduation marks for precise depth control.
Q: What drill requirements do Malco TurboShear attachments need?
Malco TurboShear attachments require a minimum 14.4V DC cordless drill or up to 7A AC corded drill with at least 1,200 RPM and a 1/4-inch or larger chuck. Both the HD and TS1 models work with standard drill chucks — no special adapters needed.
Q: Are replacement blades available for Malco snips?
Yes, Malco aluminum snips feature field-replaceable blades with a pressure-fit design that requires no special tools to swap. The 12-inch, 14-inch, and other aluminum snip models all use replaceable high-carbon steel blades.
Q: What’s the cutting capacity of Malco’s 14-inch aluminum snips?
Malco’s 14-inch aluminum snips cut vinyl siding up to 0.055 inches, aluminum to 0.035 inches, 24-gauge galvanized steel (0.028 inches), and 26-gauge stainless steel (0.018 inches). The snips deliver 3.25 inches of cutting length per stroke and weigh just 20 ounces.
