HMT

HMT (Hougen Manufacturing, Inc.) is a Michigan-based manufacturer of industrial power tool accessories and holemaking solutions, known for its VersaDrive line of quick-change impact adapters, extension arbors, and heavy-duty wrench adapters. The brand focuses on portable magnetic drilling and holemaking technology, with products engineered for use in steel fabrication, structural steel erection, shipbuilding, and heavy equipment maintenance. HMT’s product families include the VersaDrive HD (heavy-duty) and VersaDrive MAX (maximum-duty) impact adapters, as well as Rapid-Lock extension arbors, all designed to interface with standard impact wrenches and drills. Key technical attributes include HOLEMAKER TECHNOLOGY, which refers to the patented design that allows these adapters to convert a standard impact wrench into a holemaking tool by accepting annular cutters or twist drills. The adapters are built with hardened steel components and feature quick-change mechanisms for rapid bit swaps without tools. HMT products are rated for use with impact tools up to 1,000 ft-lbs of torque, and the VersaDrive MAX series is specifically engineered for higher-torque applications, with a reinforced body and heat-treated drive tangs. The brand’s extension arbors, such as the 5-inch and 12-inch Rapid-Lock models, provide extended reach for drilling in confined spaces or through multiple layers of material. HMT does not publish IP ratings for these accessories, as they are not electronic devices; instead, the focus is on mechanical durability, with specifications including drive sizes (3/8", 1/2", 3/4", 1") and shank configurations compatible with standard impact drivers. 3G Electric stocks a range of HMT VersaDrive components, including the 893G series SKUs, to support maintenance and fabrication operations worldwide. These parts are sourced directly from HMT’s authorized supply chain, ensuring genuine OEM specifications. For plant engineers and maintenance managers, HMT adapters offer a method to expand the utility of existing impact tools without investing in dedicated magnetic drills, making them suitable for field repairs, structural modifications, and on-site hole cutting in steel up to 1-inch thickness. Procurement specialists can order individual adapters or bulk quantities through 3G Electric’s global logistics network, with technical datasheets available for each SKU to verify compatibility with specific tool brands and cutter diameters.

Frequently asked questions

Common questions about HMT from 3G Electric.

What is the difference between HMT VersaDrive HD and VersaDrive MAX impact adapters?

The VersaDrive HD (Heavy Duty) series is designed for general-purpose holemaking with impact wrenches up to 600 ft-lbs of torque, featuring a compact body and standard heat-treated steel. The VersaDrive MAX (Maximum Duty) series is built for higher-torque applications up to 1,000 ft-lbs, with a reinforced body, thicker drive tangs, and a longer shank for improved stability. Both use HOLEMAKER TECHNOLOGY to accept annular cutters, but the MAX series is recommended for continuous use in structural steel or thick plate drilling.

Can HMT VersaDrive adapters be used with any brand of impact wrench?

Yes, HMT VersaDrive adapters are designed to fit standard 3/8", 1/2", 3/4", or 1" square-drive impact wrenches from any manufacturer, provided the tool meets the torque rating specified for the adapter. The adapters use a quick-change mechanism that accepts 3/8" or 1/2" hex-shank annular cutters or twist drills. Always verify the adapter’s drive size matches your impact wrench’s anvil, and do not exceed the adapter’s maximum torque rating to avoid mechanical failure.

What is HOLEMAKER TECHNOLOGY in HMT VersaDrive products?

HOLEMAKER TECHNOLOGY is HMT’s patented design that enables a standard impact wrench to function as a holemaking tool. It consists of a precision-ground shank with a quick-change collet that securely holds annular cutters or twist drills, and a built-in depth stop to control hole depth. The technology also includes a spring-loaded ejection mechanism for fast cutter removal. This allows operators to drill holes in steel without a dedicated magnetic drill press, increasing portability and reducing tool changeover time.

What materials can HMT VersaDrive adapters cut through?

HMT VersaDrive adapters are designed for use with annular cutters to drill holes in ferrous metals, including structural steel, mild steel, stainless steel, and alloy steel up to 1 inch thick. The adapters themselves are made from hardened steel and can withstand the torque required for these materials. For non-ferrous metals like aluminum or brass, standard twist drills can be used with the adapter, but the primary application is steel fabrication and maintenance.

How do I select the correct HMT VersaDrive extension arbor for my application?

HMT offers Rapid-Lock extension arbors in 5-inch (SKU 893G36, MPN 111016-130) and 12-inch (SKU 893G37, MPN 111016-300) lengths. Choose the 5-inch arbor for standard reach in tight spaces or single-layer drilling. The 12-inch arbor is suited for reaching through multiple layers of steel, deep flanges, or confined areas where the impact wrench cannot be positioned directly. Both arbors use the same quick-change collet system and accept 3/8" hex-shank cutters.

Does 3G Electric supply HMT products?
