Malco HC1E Adjustment Sleeve Set Screw HC1 Hole Cutter

Product Description

The MALCO HC1E is a replacement adjustment sleeve with set screw designed specifically as the shoe guide for the MALCO HC1 Hole Cutter. This component maintains proper bit alignment and depth control during hole cutting operations in sheet metal, including 20-gauge galvanized steel. The HC1E mounts into the hole cutter assembly and allows the operator to set and lock the pivot slide position for repeatable cuts. Fabricators and HVAC sheet metal technicians who rely on the HC1 for field or shop hole cutting will need this part when the original guide shows wear or is lost. At 0.24 inches thick, the sleeve is a low-profile, precision-fit component.

The HC1E applies to round hole cutting work in sheet metal using the MALCO HC1 Hole Cutter, which is adjustable for holes ranging from 2 to 12 inches in diameter. The HC1 installs directly into the chuck of any corded or cordless drill. This sleeve is the one replacement component that is not interchangeable across the broader MALCO hole cutter product line, including the HC2 model. It is the correct replacement only for the HC1. HVAC installers, duct fabricators, and sheet metal workers performing penetration or fitting layouts will find this a necessary service part to keep on hand.

Installation Notes

Installation of the HC1E should be performed by a sheet metal technician or qualified tradesperson familiar with the MALCO HC1 Hole Cutter assembly. Ensure the drill is unpowered and disconnected from its power source before disassembling the cutter. The set screw must be tightened securely to prevent sleeve movement during operation. Inspect the bit and bearing assembly at the same time to confirm no additional wear parts require replacement.
