BHC 18 Chuck
« on: June 09, 2020, 06:58 PM »
Has anyone had any issues with the BHC 18 Chuck? 

With the tool being Relatively new a couple of years ago, I   had to spend a good amount of time lubricating the chuck to get SDS bits to easily slip into it and "lock"

I  've recently had the chuck "let go" of an SDS masonry bit (3/16) after drilling some masonry and Pulling the bit out (there was actually a bit of pressure on the bit coming out as the dust had not completely cleared the flutes well ) 

Wondering if anyone has had similar issues and if it's possibly an SDS tooling issue? I   am using mostly SDS drill bits by a manufacturer from the US called "Tru - Cut" 

I   am often using the BHC 18 on jobsites for installing helical masonry ties and expansion anchors for pull testing activities.

Hi!

Do you lube the drill bits (with a tiny bit of grease on the rear-face/anvil end of the drill bit) regularly before inserting them and using the BHC? This should be done with SDS-Plus and SDS-Max type (rotary) hammers.

When you said you lubed the chuck, did you do so with grease or oil?

Two scenarios I can think of:

A) If you did not lube the drill bits the chuck is running dry right now, drilling dust gets in there and the locking mechanism/part of it, is stuck. Clean the chuck thoroughly

B) If you used a lot of oil/ or grease to lube the chuck, that will have mixed with the drilling dust by now, probably caked - and again the locking mechanism/part of it is stuck. Clean the chuck thoroughly.

This is actually most likely.

Third and worst case is that something broke when pulling the BHC out. But I think that is rather unlikely. It's pretty much a dry or caked stuck chuck issue.

Clean it carefully with something like WD-40, if you have pressured air in your shop, blow it carefully out - and it will work again like new.

SDS-chucks need some maintenance. I even lube the fast-fix connection on my regular drills.

Kind regards,
Oliver

I've only had my BHC about a month now. Drilled quite a few holes but no issues with bits popping out. A bit tight to get in though.

The Chuck is well lubed and has been for a while, and as the other gentlemen mentioned on this thread , at first the bits were very tight and hard to get to fit in.  I   was using it yesterday with some 3/16" bits for installing concrete screws and the bit disengaged on the pullout.   

I   have emailed Dominic who is the service tech in Canada to see if there is anything I   can do additionally on my end to try to remedy the problem without sending it in (Cleaning, checking it etc)  He's usually pretty good on helping with tool issues.
