Itm 274mc0011 Step Drill Bit 3/16 to 1-3/8 Inch

Product Description

The ITM 274mc0011 is an 11-step step drill bit designed for drilling clean, precise holes in sheet metal, thin steel, aluminum, and plastic. It handles a range of hole sizes from 3/16 inch up to 1-3/8 inch in a single tool, eliminating the need to swap bits mid-task. The stepped geometry allows the operator to stop at any of the 11 incremental sizes along the bit. It is commonly used by HVAC technicians, electricians, and plumbers when punching access holes, knockout openings, or conduit entry points in light-gauge material.

This step drill bit suits trade applications where multiple hole sizes are needed in thin-gauge sheet metal, electrical enclosures, junction boxes, and HVAC plenums or panels. The 11 steps cover a wide size range in a compact form, making it practical for field service kits and van stock. It is suited for both residential and light commercial work where drilling clean, burr-reduced holes in thin material is required.
