The TurboShear platform transforms your existing drill into a metal-cutting powerhouse, with the TSHD (Heavy-Duty) model handling 18-gauge mild steel and the standard TS1 tackling 20-gauge material. At the core of both models is a patented telescoping drill-clamp (Patent #9,649,702) that grabs onto any drill with a 1/4-inch chuck or larger — no special mounting brackets, no proprietary systems, just slide it on and tighten.
The real genius here is the 360° rotating shear head. When you’re cutting along a wall or navigating tight corners in ductwork, that rotation means you’re not fighting the tool. The lightweight aluminum-cast shear head keeps the weight down while the heavy-duty hardened carbon-steel blades do the actual cutting.
Model Specifications and Real-World Performance
The TSHD earns its “Heavy-Duty” designation with measurable capacity increases over the standard TS1:
| Material Type | TSHD Capacity | TS1 Capacity |
|---|---|---|
| Mild Steel | 18 gauge (0.048 in) | 20 gauge |
| Galvanized Steel | 18 gauge (0.052 in) | 20 gauge |
| Spiral Duct | 20 gauge (0.040 in) | 20 gauge |
| Aluminum | 14 gauge (0.060 in) | Similar |
| Copper | 0.100 in (2.55 mm) | Similar |
| Stainless Steel (non-hardened) | 20 gauge (0.032 in) | 20 gauge |
Across major seller platforms, both models pull 4.8 to 5.0 stars from approximately 40 reviews, with contractors consistently praising the clean cuts and speed. The lateral blade adjustment via 3/16-inch set-screw lets you dial in the blade clearance — clockwise for thin material, counter-clockwise when you’re pushing the thickness limits.
Your drill needs minimum 14.4V DC for cordless or up to 7A AC for corded models. That’s not asking much — any contractor-grade drill from the last decade will handle it. The wide-opening jaws work at both high and low speeds, though most users find a middle speed gives the best control without bogging down.
Where These Tools Prove Their Worth
HVAC contractors use them for straight and spiral duct installation. The rotating head really shines when you’re working in mechanical rooms or tight attic spaces where a full-size shear won’t fit.
Metal roofing crews handle standing-seam, mechanical-lock, and corrugated panels without the fatigue of hand snips. When you’re trimming panels at ridge caps or around penetrations, the TurboShear’s maneuverability beats wrestling with powered shears that weigh three times as much.
Auto-body shops use them for panel trimming and fabrication. The precision you get from controlling speed with your drill trigger gives cleaner cuts than most pneumatic tools, and you’re not tethered to an air hose.
The included components are straightforward: the shear head itself, telescoping drill clamp, adjustment knob, hex shank insert, and mounting hardware. Available accessories include replacement blade kit (Model TSHBRB), drill chuck guard (Model TSCG), replacement telescoping clamp (Model TSDC), and spacers for large motor housings.
Professional Verdict
Users report extremely fast and clean cuts in sheet metal, though some find it challenging to navigate over high ribbing on diagonal cuts. The initial setup can be tricky for some drill body shapes, but once dialed in, these attachments turn any decent drill into a specialized cutting tool.
The TSHD’s bump up to 18-gauge capacity matters for contractors working with heavier mechanical systems or structural panels. For typical residential HVAC and lighter roofing work, the standard TS1 handles everything you’ll encounter. Both models carry Malco’s Limited Lifetime Warranty covering defects in materials and workmanship under normal use conditions.
Skip these if you’re cutting hardened stainless or anything over their rated capacities — they’re sheet metal tools, not miracle workers. But for turning your existing drill into a fatigue-free cutting solution that handles 90% of field fabrication needs, the TurboShear platform delivers exactly what it promises.
Frequently Asked Questions
Q: Can I use the TurboShear with my impact driver? A: Yes, both models are compatible with impact drivers and standard cordless/corded drills, as long as they meet the power requirements and have at least a 1/4-inch chuck.
Q: How do I adjust for different material thicknesses? A: Use the 3/16” set-screw for blade adjustment — turn clockwise for thinner metals, counter-clockwise for thicker materials. Getting this dialed in makes the difference between clean cuts and jammed blades.
Q: What’s the actual difference between the TS1 and TSHD for field work? A: The TSHD increases cutting capacity to 18-gauge mild steel, compared to the 20-gauge capacity of the standard TurboShear. If you’re regularly working with mechanical ductwork or heavier panels, the TSHD saves switching to heavier tools.
Q: Will these work on my oddly-shaped drill? A: The patented telescoping clamp provides universal fit, and optional spacers handle drills with motor housings that are too large or oddly shaped. Most drills work fine with the standard clamp.
