ZELCAN SDS Max to SDS Plus Adapter for Rotary Hammer Drills, 40Cr Steel SDS Plus Drill Chuck Conversion Tool for SDS Max Demolition Hammers, Power Drill Accessory for SDS Plus Bits and Chisels, Silver

I like that it helps instead of buying two equipment you just use one

The media could not be loaded. After installing only fourteen 1/4in diameter anchors only 2in into concrete, the adapter broke. Seems like an internal spring broke. It won't retain the bits any more. Garbage. Do not recommend if it'll break after this few, small diameter holes.

Works perfect. No problems.

I used this once and it blew up into a million pieces. Luckily I got mostly through the hole I was drilling through a block wall. You get what you pay for. So I would suggest buying this if you need it for only a few holes and preferably smaller holes.

I got this as a gift yesterday for fathersday, used it once and it broke. some pins and a ball bearing fell out.This was purchased over 30 days ago unfortunately and held as a gift. I tried to get hold of zelcan, but apparently it is not possible.

Things like Tapcon drill bits only come in SDS plus so instead of having to have a second hammer drill in SDS plus this adapter makes it a piece of cake to utilize SDS bits without the need for a second hammer drill. Plus the extra range of an SDS max makes for an easier job

The first one I received broke. May have been operator error.The second one has held up well and done the job it's meant to do. Drilled a 4.5" round hole with adapter on core drill bit.

Broke in the first hole
