Drilling 5/16" holes in 4130 steel tube - jamming/binding issues
I tried dropping the RPM without success, but will gladly try again. There is no slippage, it jams and the bit/chuck/spindle/motor stops turning. Nothing is dulled. -

Drilling 5/16" holes in 4130 steel tube - jamming/binding issues
When it binds (jams), the bit/chuck/spindle/motor stops. Nothing breaks. Same drill brand, same stock - but maybe a new bit brand now that I think of it which is a huge possibility. The tubing is clamped down in a self centering jig and doesn't move. I'll try my older bits in case it is a new... -

Drilling 5/16" holes in 4130 steel tube - jamming/binding issues
The bit jams in the tubing and stops the chuck/spindle/motor. The belt isn't slipping. -

Drilling 5/16" holes in 4130 steel tube - jamming/binding issues
I have been drilling 5/16" holes in 4130 steel tube (1/16" wall) for many years with HSS bits and a Harbor Freight drill press set at 920 RPM. There has been occasional binding, but nothing to problematic. Now, however, even brand new bits are binding when it punches through every time. I've... -

Best tool for quickly cleaning up cuts on tubing
Thanks for the input. I looked at the ideas and didn't see anything that looked like it did the light work I need better/quicker than the disc sander. Hand tools are definitely not what I'm looking for (we already use an ID deburrer). We can easily do a couple hundred tubes in an hour. I guess...- skiffe

Best tool for quickly cleaning up cuts on tubing
My business is centered around cutting lots of 1/16" wall tubing in diameters from 1/2" to 1" and lengths from 1.5 inches to 6 feet - 6061 and 6063 aluminum, 4043 steel, and carbon fiber. I'm happy with my saw but the cuts still need a quick grind to smooth out the sharp edges. I've been using a...- skiffe

Tube Cutting Machine Advice
After reading the manual, watching tuning videos, and giving it a go it is still cutting at an angle. I think it may be the pivot and I don't have the equipment to fix it. I may wait for black friday/cyber monday and give one of the metal cutting saws like the dewalt of makita a try and dream of... -

Tube Cutting Machine Advice
The problem may be that I have no experience in a shop but jumped right in to full time design and manufacturing. It has been successful but I have not been able to make the proper adjustments to get a straight cut anymore (it once cut straight-ish). I use quality blades and it is mounted on my... -
