How do you get that gunk out of your milling table’s T-slots?  It’s almost impossible to clean the shavings out of these oily recesses — unless you’ve got this scraper designed just for the purpose.  Its T-shaped head matches the shape of the table slots to scrape the metal debris away.

J.W. Winco makes the blade from hardened chrome-vanadium steel and the handle from red and black cadmium-free plastic.  Why tout your product as cadmium free?  Used in some pigments, cadmium can be an environmental hazard.

This product is hard to find — you might have better luck making one yourself — but if you go to J. W. Winco’s website you can order a scraper that fits 14-20mm (9/16″ to 3/4″) T-slots for $6.70 or a scraper that fits 22-32mm (7/8″ to 1-1/4″) T-slots for $14.64.

    I’ve alway just grabbed an air hose and blew them out. If you clean your machine at the end of the day it’s just not that hard to clean out. If you let it sit then you’ll have problems.

    Or you could use your milling machine to mill your own t shaped scraper out of some scrap steel……….

    Our first assignment at tech school was to make a t-slot cleaner using only a file and hacksaw. It’s probably my most frequently borrowed tool wherever I’ve worked.

    I agree with PutnamEco that it’s easiest to just clean your machine at the end of the day. But when you come upon a machine that’s encrusted in grease and chips, not uncommon in my experience, it’s time to pull out the big guns.

    Please be careful cleaning metal chips with air–it’s really dangerous and personally I don’t think it’s worth the risk, nor does it really CLEAN anything, it merely moves the mess elsewhere, just like my neighbor’s leaf blower. Better to use a cheap chip brush and a dustpan. Most T-slot clamp sets come with a slot cleaning tool anyway, and how do you use a mill without those?

    Yeah, I made one of these out of some scrap aluminum sheet stock in about five minutes.

    Using an airgun would be dangerous. I also think it might violate OSHA codes.
