Heavy-duty structural steelwork and hard plate drilling quickly wear out standard HSS cutters, leading to frequent downtime and excessive tooling overheads. The HMT CarbideMax™ 40mm TCT Broach Cutter 5-Piece Set (MPN: 108030-5SET) resolves this efficiency bottleneck by utilising industrial-grade carbide tips to pierce tough alloys effortlessly while extending tool life up to tenfold.

Benefit-Driven Technicals
-
Sandvik Tungsten Carbide Teeth: Premium-grade carbide tooth tips maintain an ultra-sharp cutting edge on high-tensile steels and wear plate, offering up to 10x longer service life than conventional HSS tooling.
-
40mm Working Depth: Designed for deep single-pass penetration, allowing smooth broaching through structural plate and heavy section beam flanges up to 35mm thick without binding.
-
Advanced Triple-Edge Geometry: Optimised tooth profiling distributes cutting loads evenly, delivering up to 64% faster drilling speed alongside smooth, chatter-free operation.
-
Thin-Wall Alloy Construction: Reduces overall material removal per revolution, requiring significantly less motor torque from your magnetic drill and lowering operator fatigue.
-
Universal 19.05mm Weldon Fitment: Precision machined shank guarantees immediate compatibility with standard magnetic drilling machines without needing specialised adaptors.

EWS Expert Note
When operating TCT broach cutters, maintaining correct RPM and continuous lubrication is critical. Run your mag drill at higher speeds than you would for standard HSS cutters, but enter the cut slowly to prevent carbide chipping. Always apply a high-viscosity cutting paste rather than light oil; paste clings to the inner core, cooling the carbide tips directly and ensuring reliable slug ejection upon completion.
Pros & Cons
Pros:
-
Exceptionally long working life on tough materials like stainless steel and high-tensile alloys.
-
Significantly faster penetration rates, drastically reducing hole-cycle times on large site builds.
-
Includes organised STAKIT foam insert to keep workshop inventory secure and accessible.
Cons:
-
Not suitable for hand-held non-magnetic drills; requires a rigid magnetic drill stand or fixed workshop machine.
-
Brittle carbide teeth will chip if subjected to side loads or uneven manual feeding on interrupted cuts.
Technical FAQs
Q: Will this cutter set fit my existing magnetic drilling machine?
A: Yes, all cutters in the HMT 108030-5SET feature a standard 19.05mm (3/4") Weldon shank. This makes them directly compatible with almost all standard commercial magnetic drills without requiring separate arbors or specialised shank adaptors.
Q: Can I use these CarbideMax cutters on non-ferrous metals like aluminum?
A: While TCT cutters can pierce non-ferrous materials, soft metals like aluminium tend to gum up the fine teeth layout, causing clogging. They perform best on hard ferrous materials including structural carbon steel, alloy plate, and stainless steel.
Q: How do I know which pilot pin to use with the set?
A: The set includes two pilot pins tailored to the cutter bores. Use the slimmer pin for the 12mm–17mm cutter range and the thicker pin for cutters 18mm and above. Both pins ensure precise centering and effective slug ejection.
