[email protected] Reaming holes in aluminum (feeds/speeds)Aug 28, 2017 · Open up your drill like Gkoenig said but slow down your reamer to S2000-1500 and feed between F5.0 - F10.0 as a starting point and work your way up. Make sure your reamer is not sticking too far out when reaming the holes. You can also use a G85 boring cycle where it feeds in and feeds out or use a drilling cycle G81 where it feeds in and

Depending on depth, use diameter at top of part to determine chipload. For example, if using 1/4" diameter, 90° point and depth is 1/8", calculate the
Increase speed - also try reduced feed. 2. EXCESSIVE CUTTING EDGE WEAR:Wrong feeds & speeds Rough cutting edge Insufficient coolant:Increase feed (should always be over .001" per tooth) - especially when machining ductile or free machining materials. - Also try reduced speed.
