ER16 Collet Chuck with flanged bottom, opening from .012” to .416” (.3mm to 10.3mm). Accepts all standard ER-16 collet sizes. COLLETS NOT INCLUDED.

I think it will depend on how deep you go too. But I double feed and half to 2/3 rpm all the time with a reamer if the hole is prepared right. In alum. You can increase that feed to 50ipm no problem with a peck cycle, (*c* drill). Although it would depend on the depth, coolant and such. First time I showed it to someone they though I was crazy.

Should be approximately 50% of the speed used for drilling the same material. Faster speeds are generally not an advantage , but may be possible in exceptionally rigid and efficient designs. Chatter degrades the surface finish and must be strictly avoided.

So if I drilled a hole at 5000rpm with a 30im feedrate, the reamer would be be 2500rpm and 60im?...that seems fast to me.

I did some searching and found that most of you use what I have always used in terms of speeds and feeds for reaming. But I came across this today and it seemed to be way to fast in the feed area:

Should be approximately 100% greater than the feed used for drilling the same material. Insufficient feed may degrade the finish and roundness of the hole and increase tool wear.

Standard HSS stub drill...for my example I was using a *C* drill(for a 1/4 reamer) which I have set to 6000rpm and 30im.

In a mild steel like 1018 or sumthin, I would run that drill around 1400rpm and around 6 IPM...so 700rpm ream and 12 IPM.

Something I was told years ago for reaming 2/3 the speed and 3 times the feed of the drill. It has always seemed weird, and no I do not do it. I feed drills up to 20 to 50 ipm depending on the drill, size, and material. Going 60 to 150 ipm on a reamer just does not seem right, but this rule was for bridge ports and conventional lathes.

I plow MA Ford carbide reamers in our reamed holes pretty hard; I would say that 150-175% of the feed I would drill at and probably 75% of the speed

Yeah, I know that, I'm in the middle of making a custom tool library and was just trying to see what the industry standard/average is.

ER Collet Chucks are a great way to hold small diameter parts. The ER16 collet with a flange, adds stability for larger round parts from .012” to .416” (.3mm to 10.3mm) diameter. Has a threaded through hole to add a depth stop and a brass tipped set screw on the side to lock it in place. Made from 303 stainless steel for durability and corrosion resistance. Use one or add multiple collet chucks for a multi-part setup. Use on quick-swap Loc-N-Load™ plates or on existing 1” or ½” hole patterns and for ¼-20 or M6 threaded holes.

reamers are talking a light cut so the feed doesn't affect it much. Sometimes you get a better finish going higher feed and it takes less time.

Straight Flute reamers may have advantage in blind holes, since lefthand spiral flutes tend to push swarf forward. Generally speaking the standard range of reamers will suffice for reaming most ferrous and non-ferrous metals.
