Product Description
Milwaukee SHOCKWAVE Impact Duty 4mm - 20mm Step Bit
Model Number: 48-89-9263
The Milwaukee 48-89-9263 is a SHOCKWAVE Impact Duty Metric Step Bit that drills a full range of hole sizes with a single cone-shaped bit, covering 4mm through 20mm in 2mm steps, which is nine different hole diameters on one bit. A step bit's stepped, cone-shaped profile lets it start a small pilot hole and be driven deeper to open the hole to progressively larger diameters, so one bit replaces a whole set of individual twist bits when drilling thin material like sheet metal, electrical enclosures, and plastics. The stepped design also deburrs as it cuts and gives clear visual size stops, so the operator can drill to an exact diameter and stop at the right step. This is the Impact Duty version, engineered specifically for the high torque and impact of a cordless impact driver, and Milwaukee rates the SHOCKWAVE step bits for up to 5X longer life than standard step bits.
The bit is built around impact performance and durability. The SHOCKWAVE shank is optimized to absorb the peak torque of an impact driver and flex rather than snap, which is what prevents the breakage that ends the life of ordinary bits under impact use, and the 1/4 in. hex shank locks securely into an impact driver or drill/driver chuck and bit holder. It is compatible with both impact drivers and drill/drivers, so it works with the tools already in the kit. The optimized flute and tip geometry drives fast, clean holes and clears chips as the bit steps up through the material.
This step bit is a versatile, space-saving accessory for electricians, HVAC technicians, metal fabricators, and maintenance professionals who drill a range of hole sizes in thin metal and plastic and want one bit that does the work of many, with the impact-rated durability to hold up in a cordless impact driver. Covering the common 4mm to 20mm metric range, it handles the conduit knockouts, connector holes, and mounting holes that come up across electrical and mechanical work. For anyone drilling metric holes in sheet material, it is a durable, do-it-all bit.
