Hole Saw for Impact Drivers

The Unibor 28128 is a carbide-tipped hole saw built for use with impact shanks. It suits tradespeople who need fast, clean holes in metal or wood on site. The Speedcut design reduces cutting resistance during heavy-duty drilling tasks.

Impact Shank Limits

An impact shank transfers high torque directly to the saw body, so the workpiece must be clamped securely to prevent binding. The carbide tips handle abrasive materials but can chip if the saw wanders off-centre during the cut.

7/8 Inch Cutting Diameter

The saw cuts a precise 7/8 inch hole, making it the correct choice only when that exact diameter is required. Buyers needing larger or smaller holes must select a different size from the range.

Questions about this item

Which version of the Unibor 28128 Speedcut hole saw should I choose for a 7/8 inch cut?

The 28128 model is a single 7/8 inch diameter carbide-tipped hole saw with a 3/16 inch depth of cut, so no other version or capacity is offered for this part number.

What does the 7/8 inch diameter mean when the saw is mounted in an impact driver?

It produces a precise 7/8 inch hole up to 3/16 inch deep in metal, and the carbide teeth resist wear during high-torque impact driving.

What shank standard does the impact shank follow and what torque can it handle?

The impact-rated shank fits standard 1/4 inch hex quick-change chucks used on impact drivers and is built to withstand the repetitive hammer blows of those tools.
