MPN: 75861

Weight: 1kg

Overview:

The Tolsen 9-piece bi-metal hole saw set covers six common cutting diameters, from 19mm to 57mm. It pairs with two included hex shank arbors and an adapter, giving you a practical kit for a range of general cutting tasks.

Bi-metal hole saws combine high-speed steel teeth with a flexible alloy steel body. This construction handles wood, plasterboard, PVC, and thin non-ferrous metals without needing multiple specialist tools.

Both arbors come fitted with HSS pilot drills that centre the saw before the teeth engage. This reduces wander and helps produce cleaner holes from the start of each cut.

Key Features and Benefits

• Six bi-metal hole saw sizes: Diameters of 19mm, 22mm, 29mm, 38mm, 44mm, and 57mm cover the most common domestic and trade cutting requirements.
• HSS pilot drills on both arbors: High-speed steel pilot drills register the centre point before cutting begins, decreasing the risk of the saw wandering off-mark.
• 3/8" (9.5mm) hex shank arbor: Compatible with hole saws in the 14-30mm range, secured by a hex shank for a firm chuck grip.
• 7/16" (11mm) hex shank arbor: Designed for larger hole saws from 32-210mm, with the same hex shank design for positive engagement.
• Adapter included: Provides additional compatibility between components within the set.
• Bi-metal construction: HSS teeth bonded to a flexible alloy steel body allow cuts through wood, plasterboard, PVC, and thin non-ferrous metals.
• Hex shank drive: Both arbors use a hex shank to seat firmly and resist slipping under load.
• Nine-piece set: Six hole saws, two arbors, and one adapter in a single kit for everyday installation and repair work.

How to Use

• Select the size: Choose the hole saw that fits the diameter required for your job.

• Fit the arbor: Thread the chosen hole saw onto the correct arbor and tighten it securely before fitting to your drill chuck.

• Mark the centre: Mark the centre point of the required hole clearly on the workpiece before drilling.

• Start slowly: Begin at a low speed so the pilot drill seats itself before the saw teeth contact the material.

• Apply steady pressure: Keep steady, moderate pressure throughout the cut without forcing the saw.

• Clear the waste: On deeper cuts, back the saw out periodically to clear chips and allow the teeth to cool before continuing.

Frequently Asked Questions (FAQs)

• What drill speed should I use with a bi-metal hole saw?
  The correct speed depends on both the diameter and the material. Larger diameters need slower speeds. As a guide, wood suits 400-600 RPM and thin metals work better at 50-150 RPM. Reducing speed as the diameter increases prevents overheating and helps the teeth last longer.

• Can bi-metal hole saws cut ceramic or porcelain tiles?
  No. Ceramic and porcelain tiles require diamond-tipped hole saws. Bi-metal teeth are not hard enough for fired ceramics and will blunt on contact. Always match the saw type to the specific material you are cutting.

• How do I remove the slug from inside a hole saw after cutting?
  Most hole saws have a small slot or ejector hole in the side of the cup body. Push a screwdriver or rod through this opening to push the cut slug free. Avoid pressing the slug out with your fingers near the teeth.

• What is the difference between bi-metal and carbide-tipped hole saws?
  Bi-metal saws use HSS teeth on a flexible steel body and work well in wood, plastics, and soft metals. Carbide-tipped saws are harder and wear more slowly in abrasive materials such as fibre cement or stainless steel, but they cost considerably more per saw.

• Why does my hole saw cut slowly or burn the material?
  Burning or slow cutting is usually caused by running at too high a speed, applying excessive downward force, or using a saw with dull teeth. Try reducing speed, easing the pressure, and backing the saw out more frequently to clear chips and reduce heat build-up.
