Hammer Drill Adaptor – SDS Plus to SDS Max – LT-SPM1 | Lerin Tools

The Lerin Tools LT‑SPM1 hammer drill adaptor allows an SDS Plus hammer drill to drive SDS Max accessories. It plugs into your SDS Plus chuck and provides an SDS Max interface, so you can run selected SDS Max tools where appropriate without buying a new SDS Max drill straight away.

Made from hardened steel, this adaptor is built for trade use and high impact loads. It is ideal for tradies who want to tackle heavier applications with their existing SDS Plus hammer drill while planning a future upgrade to a full SDS Max setup.

FAQs
What does this adaptor do?
It allows you to connect selected SDS Max accessories to an SDS Plus hammer drill by converting the SDS Plus shank to SDS Max.

Is it safe to use all SDS Max bits in an SDS Plus drill?
No. SDS Max accessories are designed for more powerful tools. Only use accessories that the drill and accessory manufacturers consider suitable for your SDS Plus drill and stay within the drill’s capacity.

Will it fit my drill?
This adaptor fits drills with an SDS Plus chuck. It will not fit SDS Max drills (for that you use LT‑SMP1 instead). Check your drill is SDS Plus.

Does this replace an SDS Max drill?
No. It helps in specific situations, but a real SDS Max drill is the correct tool for heavy SDS Max chisels and large bits. Use this adaptor as a convenience, not a full replacement.
