12-piece hole saw kit for light-duty cutting

The KATA KT89042 kit contains 8 hole saw blades ranging from 19 mm to 64 mm, two mandrels and a hex key. Heat-treated carbon steel with a black anti-rust coating gives aggressive, clean cuts in soft wood, drywall, plywood and thin PVC. The set is designed for home DIY, cable routing, pipe openings and similar light-duty tasks. It works with standard electric drills, impact drills and bench drills.

Suitable for DIYers cutting soft materials.

This kit suits homeowners and hobbyists who need quick, precise holes in wood, plastic or drywall up to about 25 mm deep. It will not cut metal, tile, stone, concrete or hard wood. Users requiring deeper cutting capacity or abrasive-material performance should look at specialised hole saws or core drills. The included mandrels fit common drill chucks for fast size changes.

Eight diameters from 19 mm to 64 mm cover common

The blades handle cable entries, vent holes, recessed-lighting prep and speaker cut-outs in a single pass up to 25 mm depth. Beyond that depth the teeth lose clearance and cutting slows. Hard or abrasive materials dull the edges quickly, so the kit is limited to soft wood, thin plywood and thin PVC panel. For larger diameters or tougher stock a different tool is required.

Questions about this item

What drill chuck size do the two included mandrels need?

The kit supplies two mandrels designed for a standard electric or impact drill; the shank fits the chuck on most common drills used for wood and PVC work.

Can the 64 mm blade cut through the same 25 mm maximum depth as the smaller blades?

Yes, every saw blade in the set — from 19 mm up to 64 mm — is rated for cutting depths up to about 25 mm in soft wood, plywood, drywall and thin PVC.

After drilling a test hole in scrap plywood, what should I check to confirm the 32 mm blade is cutting cleanly?

The hole edge should be smooth with no tear-out, the blade should not bind, and the cut depth should reach the 25 mm limit without overheating the steel.
