Unibor 28136 Speedcut Hole Saw
The Unibor 28136 is a carbide-tipped hole saw built for impact-rated shanks. It targets metalworkers and maintenance crews who need clean cuts in sheet steel and plate. The 1.1/8 by 3/16 inch cutting profile suits pipe-entry and conduit jobs. New condition means full tooth geometry and no prior wear.
Impact shank fits direct to driver
The impact shank locks into compatible drivers without an adaptor, so changeover takes seconds. Carbide teeth resist heat but can chip if the cut wanders or feed pressure spikes. Keep the saw perpendicular and use steady pressure to avoid binding. Lubricant extends life in thicker material.
Carbide limits in hard alloys
Carbide tips handle mild steel and stainless up to moderate hardness, but hardened plate or abrasive composites will dull them quickly. The 3/16 inch depth of cut restricts use to thin-wall sections. No internal coolant passage means heat builds fast in deep holes. Users needing deeper cuts or tougher alloys should select a different tool.

Questions about this item
How can I confirm the 28136 Speedcut hole saw cuts cleanly after mounting it on my impact driver?
The carbide-tipped teeth should produce smooth, burr-free holes in steel at 1.1/8 inch diameter without wandering or overheating when the shank is fully seated in the impact chuck.
What comes with the 28136 and what must I supply separately?
The box contains the 28136 Speedcut carbide-tipped hole saw with its impact shank; you will need a compatible impact driver or pneumatic tool and cutting lubricant.
Should I choose the 28136 1.1/8x3/16 model or a different size for 16 mm plate?
The 28136 is built for 1.1/8 inch diameter holes with a 3/16 inch cutting depth, so select it only when those exact dimensions match the job.
