Hammer Drill Adaptor – SDS Max to SDS Plus – LT-SMP1 | Lerin Tools

The Lerin Tools LT‑SMP1 hammer drill adaptor converts your SDS Max rotary hammer into a tool that can run SDS Plus bits. Instead of carrying two drills, you can plug this adaptor into your SDS Max drill and use standard SDS Plus masonry bits and accessories for lighter and general‑purpose drilling.

Built from hardened steel, the adaptor is designed for trade use with strong impact resistance and long service life. It gives you more flexibility on site, so your SDS Max drill can handle heavy chiselling and SDS Plus drilling just by swapping the adaptor, helping you save time, reduce tools and work smarter.

FAQs
What does this adaptor do?
It converts an SDS Max chuck to accept SDS Plus bits, so you can use SDS Plus drill bits and accessories in an SDS Max drill.

Will it fit my drill?
This adaptor fits hammer drills and rotary hammers with an SDS Max chuck. If your drill is SDS Plus only, you don’t need this adaptor. Check the shank type on your drill before purchasing.

Can I use hammer mode with this adaptor?
Yes, it is intended for hammer drilling with SDS Plus bits in masonry and concrete. Always stay within the bit and drill manufacturer’s recommended modes and capacities.

Does this replace an SDS Plus drill?
It allows an SDS Max drill to cover many SDS Plus drilling tasks, but a dedicated SDS Plus drill may still be lighter and more compact for some jobs. This adaptor is ideal when you want to do more with your existing SDS Max tool.
