Robert Bosch Tool Group TC1 Carbide Zip Bit 10 Pack

Product Description

The ROBERT BOSCH TOOL GROUP TC1 is a 1/8 inch solid carbide zip bit designed for making irregular cuts in hard tile and masonry surfaces. It handles angles, pipe holes, and outlet cutouts through ceramic wall tile, cement board, cultured marble, and plaster up to 1 inch thick. The solid carbide construction provides the hardness needed to cut through dense materials without dulling quickly. This bit is intended for use by tile setters, remodelers, and contractors who need precise freehand cuts in wall surfaces during renovation or new construction work.

This zip bit is engineered for use with RotoZip, RotoMite, and SpiraCut rotary spiral cutting tools. It excels in tile remodel situations where a single continuous cut must pass through ceramic wall tile and the attached drywall or cement backer board simultaneously. Typical applications include cutting outlet box openings, plumbing penetrations, and angled contour cuts in tiled walls. The package contains 10 bits, making it practical for multi-room jobs or high-volume tile work where bit life is consumed quickly on hard materials.

Installation Notes

This bit is installed and operated by tile setters, remodelers, and general contractors using compatible rotary spiral cutting tools. Ensure the host tool is powered off and unplugged before changing bits. Eye protection and dust control measures are recommended when cutting ceramic tile or cement board, as these materials produce fine silica-containing dust. Do not force the bit through material faster than the tool and bit can clear debris, as this can cause premature bit failure or surface chipping.
