Hole saw adapter Makita D-17619 SDS+ for 32–76 mm hole saws

The Makita D-17619 SDS+ hole saw adapter enables the use of round hole saws with SDS+ rotary hammers and drills. It accepts hole saws with diameters from 32 mm to 76 mm and provides a secure mechanical connection between the hole saw and the SDS+ tool. The adapter is intended to transfer torque reliably for cutting larger circular openings and to simplify tool changes when working with SDS+ machines.

Advantages

This adapter offers straightforward compatibility with SDS+ chucks and a range of hole saw diameters, allowing users to fit a single arbour to multiple hole saws. It delivers stable torque transfer suitable for demanding drilling tasks and reduces downtime through quick installation and removal. The adapter's design supports safe attachment of round hole saws and helps maintain concentric cutting for cleaner holes.

Suitable for

• Creating circular openings in wood, plastic, and non-reinforced materials using SDS+ rotary hammers or drills
• Installation tasks requiring larger bore holes such as plumbing, electrical boxes, and HVAC penetrations
• Workshop and site work where a single SDS+ machine is used to perform multiple hole saw sizes

When it may not be suitable

This adapter is not intended for use with diamond or abrasive hole saws designed for wet cutting of masonry or reinforced concrete; those applications require dedicated arbors and cooling. It may also be unsuitable when extremely high-speed drilling or precision fine-bore work is required, as SDS+ rotary hammers produce different vibration and speed characteristics compared with dedicated slow-speed hole saw drills.

Key specifications

• Compatible hole saw diameter range: 32–76 mm
• Shank type: SDS+ compatible
• Function: Adapter/arbour for round hole saws
• Primary use: Transmission of torque between SDS+ tool and hole saw

How to use

Install the adapter into the SDS+ chuck of the rotary hammer or SDS+-capable drill until it locks in place according to the tool manufacturer's instructions. Attach the selected hole saw (within the 32–76 mm range) to the adapter by engaging its internal thread or mounting interface and securing with the supplied pilot bit or locking mechanism if applicable. Start drilling at low speed to establish the pilot position, then apply steady pressure and appropriate speed for the material being cut. Periodically withdraw the hole saw to clear debris and avoid overheating. Remove the adapter from the tool after use and inspect mounting surfaces for wear.

What to consider before purchase

• Confirm that your drill or rotary hammer accepts SDS+ shanks
• Verify the hole saws you intend to use fall within the 32–76 mm diameter range
• Check whether the materials you will cut require a specific type of arbor or cooling (e.g., masonry, reinforced concrete, or wet cutting)

Usage recommendations

Use appropriate personal protective equipment, select the correct pilot bit for the hole saw, and match drilling speed and pressure to the workpiece material. For prolonged cutting or hard materials, allow intervals for cooling and clear chips frequently to maintain performance and prolong adapter life.
