Tolsen Hole Saw Mandrel SDS Plus Fits Holesaw 32mm to 152mm 75703

Tolsen Hole Saw Mandrel SDS Plus 32-152mm - 75703

MPN: 75703

Barcode: 6933528778363

Dimensions: 270mm x 70mm x 30mm

Size: 32-152mm

Weight: 250g

Overview:

The Tolsen 75703 is a heavy-duty SDS-PLUS hole saw arbor built for large-diameter drilling in masonry and concrete. It connects your SDS-PLUS rotary hammer drill to hole saws ranging from 32mm to 152mm, giving you a stable, wobble-free cutting platform on tough construction materials.

At the centre of the arbor sits a 1/4" x 75mm M2 HSS pilot drill with a 135° split point. This geometry locks the bit on contact, stopping it from wandering across hard or uneven surfaces before the hole saw engages. The result is a clean, accurately positioned hole from the first pass.

The SDS-PLUS shank delivers a quick, secure connection to your rotary hammer. Designed for high-torque applications, it handles the demands of cutting wide openings in brick, block, and similar construction materials without slipping or play in the chuck.

Key Features and Benefits

• SDS-PLUS shank: Provides a quick, secure connection to SDS-PLUS rotary hammer drills for high-torque cutting.
• Hole saw compatibility: Fits bi-metal and carbide hole saws from 32mm to 152mm in diameter.
• M2 HSS pilot drill included: A 1/4" x 75mm pilot drill comes fitted as standard.
• 135° split point geometry: The pilot drill tip engages immediately on contact, preventing wandering on hard surfaces.
• Stable cutting platform: The arbor body holds large hole saws firmly, reducing vibration and deflection during cutting.
• Built for masonry work: Designed specifically for drilling wide holes in concrete, brick, and building block materials.
• Heavy-duty construction: Made to withstand the torque demands of large-diameter hole saw cutting in tough substrates.

Specs & Attributes

• Shank type: SDS-PLUS
• Pilot drill: M2 HSS, 1/4" x 75mm, 135° split point
• Hole saw compatibility: 32mm - 152mm
• Overall Dimensions: 270mm x 70mm x 30mm

Typical Applications

• Drilling large-diameter holes in concrete walls and floors
• Cutting wide openings in brick and building block
• Creating cable and pipe entry points in masonry structures
• Installing conduit, soil pipe, and drainage fittings through walls
• Renovation and construction projects requiring large-bore masonry holes
• Fitting air bricks, ventilation grilles, and wall sleeves

How to Use

• Fit the hole saw: Thread your chosen hole saw (32mm-152mm) onto the arbor body and tighten securely.

• Insert into the drill: Push the SDS-PLUS shank into your rotary hammer until it clicks and locks in place.

• Mark your position: Mark the hole centre point clearly on the masonry surface before drilling.

• Start drilling: Apply steady, even pressure. Allow the pilot drill to engage first before the hole saw teeth make contact.

• Complete the cut: Keep steady forward pressure throughout the cut. Withdraw the arbor and hole saw once the cut is complete.

Frequently Asked Questions (FAQs)

• What is an SDS-PLUS arbor and why do I need one?
  An SDS-PLUS arbor, also called a mandrel, is the adapter that connects a hole saw to an SDS-PLUS rotary hammer drill. Standard drills with a keyed or keyless chuck cannot accept SDS shanks, so if you want to use a hole saw with a rotary hammer, you need an SDS arbor. The SDS connection transmits far more torque than a standard chuck, making it suited to large-diameter cutting in masonry.

• What is the difference between SDS-PLUS and SDS-MAX?
  SDS-PLUS and SDS-MAX are two different shank sizes for rotary hammer drills. SDS-PLUS shanks are 10mm in diameter and found on the most common hammer drills for general construction work. SDS-MAX shanks are larger at 18mm and are used on heavy-duty demolition and core drilling machines. This arbor uses an SDS-PLUS shank, so it fits SDS-PLUS rotary hammers only.

• Can I use this arbor with bi-metal and carbide hole saws?
  Yes. The arbor accepts bi-metal hole saws in the 32mm to 152mm range. Always check that your hole saw has a compatible thread fitting for the arbor before use.

• What does the 135° split point on the pilot drill mean?
  The split point angle refers to the geometry ground into the tip of the pilot drill. A 135° split point creates a smaller initial contact area, which means the bit starts cutting immediately rather than skating across the surface. This reduces the need to centre-punch before drilling and gives you a more accurate start position.

• Can this arbor be used on wood or metal as well as masonry?
  The arbor body is compatible with standard hole saw threads and can physically be used in various materials. However, it is designed primarily for use with SDS-PLUS rotary hammer drills cutting masonry. For wood or thin metal, a standard drill and arbor combination is typically the more appropriate choice, as rotary hammers are not always suited to those applications.

Summary

The Tolsen 75703 SDS-PLUS hole saw arbor lets you attach large hole saws from 32mm to 152mm directly to your SDS-PLUS rotary hammer. With a fitted M2 HSS pilot drill featuring a 135° split point, it gives you accurate, controlled starts on masonry, brick, and concrete. If you regularly cut wide-bore holes in construction materials, this mandrel gives you the connection and stability to do it cleanly.
