Product Description
The IRWIN 4935107 is a 3/16-inch multi-material jobber-length drill bit engineered for professionals who need to move through more than one substrate in a single job. Built with a diamond-ground, 4-facet carbide tip, it maintains sharp cutting edges through demanding applications. Double-milled flutes channel drilling debris out of the hole continuously, reducing clogging and heat buildup. The bit is rated for standard rotary drilling and is tough enough to run in hammer drills, making it a practical single-tool solution across mixed-material assemblies. Electricians, plumbers, and general contractors reaching for one bit on a multi-surface layout will find this a reliable choice.
This bit is suited for residential and light commercial work where drilling through combinations of brick, block, tile, metal, wood, plastic, and marble is required in a single pass or across tasks on the same job site. It fits standard 3/8-inch and 1/2-inch keyed or keyless chucks and is compatible with both corded and cordless rotary drills as well as hammer drills. The jobber length keeps it maneuverable in confined spaces while still providing enough reach for typical through-wall or through-slab applications.
Key Features
- Diamond-ground 4-facet carbide tip for sharp, consistent cutting across multiple materials
- Rated for brick, block, tile, metal, wood, plastic, and marble
- Double-milled flutes evacuate debris continuously to prevent clogging
- Compatible with both rotary drills and hammer drills
- Jobber length balances reach with control in tight work areas
Compatibility
Designed as an OEM-style replacement or direct-use bit for standard rotary and hammer drills accepting a round or hex shank in residential and light commercial applications across multiple substrate types.
Installation Notes
This bit is installed and used by electricians, plumbers, HVAC technicians, and general contractors. Secure the bit fully in the chuck before drilling and confirm the chuck is tightened to prevent slippage. When drilling masonry or tile, let the bit do the work at moderate speed to avoid tip overheating. Wear appropriate eye protection and dust control measures when drilling into masonry, concrete block, or marble.
