Itm 255h32 Metal Drill Bit 1/2x6 in Impact Hex Shank

Product Description

The ITM 255h32 is an M2 high-speed steel jobber drill bit built for impact drilling in metal. It features a 1/4-inch hex shank that seats directly into impact drivers, reducing slippage and improving torque transfer during aggressive drilling cycles. The M2 steel composition provides good red hardness, allowing the bit to maintain its cutting edge at elevated temperatures generated by high-speed impact drilling. At 1/2-inch diameter and 6 inches in length, this bit handles through-hole and deep drilling tasks that standard jobber bits may not reach. It is suited for electricians, plumbers, HVAC installers, and general trade professionals who use impact drivers as their primary drive tool on metal drilling applications.

This drill bit is used in residential and commercial jobsite applications where drilling through steel studs, sheet metal, angle iron, or light structural steel is required. The hex shank design makes it compatible with quick-change chuck systems, allowing fast bit swaps without a dedicated drill chuck. Typical install scenarios include running conduit, drilling pipe hangers, and making penetrations through metal framing.

Key Features

• M2 high-speed steel construction retains cutting edge under high-heat impact drilling conditions
• 1/4-inch hex shank compatible with standard impact driver quick-change chucks
• 1/2-inch cutting diameter suitable for conduit knockouts, pipe penetrations, and structural metal work
• 6-inch jobber length provides extended reach for deep or obstructed drilling locations
• Designed specifically for impact driver use, reducing cam-out and shank deformation compared to round-shank bits

Compatibility

Designed for use with impact drivers and drill/drivers equipped with a 1/4-inch hex quick-change chuck, suitable for drilling through ferrous and light structural metals in trade and construction applications.

Installation Notes

This bit is installed and used by electricians, plumbers, HVAC technicians, and other trade professionals using impact drivers on metal substrates. Ensure the hex shank is fully seated and locked in the chuck before operation. Use appropriate cutting fluid or lubricant when drilling thick or hardened steel to extend bit life and reduce heat buildup. Wear proper eye protection and secure workpieces before drilling.
