Unibor 28118 Speedcut Carbide Hole Saw
The Unibor 28118 Speedcut carbide-tipped hole saw is built for metalworkers and maintenance crews who need clean holes in steel plate and structural sections. Its impact-rated shank allows use with hammer drills and high-torque drivers without slipping. The tool arrives new and ready for immediate workshop or site deployment.
Impact Shank Integration and Cutting Clearance
The impact shank locks directly into standard 1/2in or larger chuck jaws, removing the need for a separate arbor or pilot drill. Carbide teeth cut through mild and stainless steel, freeing the operator from frequent bit changes when switching between material grades. No additional drive adapters are required for the listed shank format.
Sustained Cutting Behaviour in Steel
Carbide tips maintain edge geometry during extended drilling cycles, reducing heat buildup that would dull high-speed steel equivalents. The tooth profile ejects chips continuously, preventing binding when drilling through-holes thicker than the cutting depth. Performance remains consistent across repeated holes in structural sections.

Questions about this item
How deep can the 28118 carbide-tipped hole saw cut before it hits its limit?
The 28118 Speedcut hole saw has a 3/16in cutting depth, so that is the maximum material thickness it can penetrate in a single pass.
Does the impact-rated shank run hot or vibrate heavily during extended use?
The carbide tips and impact shank are designed for high-torque tools, reducing heat build-up and vibration during all-day drilling.
Which power tools accept the 28118's impact shank directly?
The 28118 fits any impact driver or drill with a standard 1/4in hex chuck, so no adapter is needed.
