Complete Guide to Drilling and Tapping Stainless

The problem is that many stainless steels 304 and 316 in particular can get harder and tougher to cut as you work if the cutting tools are improperly applied. This phenomenon, known as work hardening, occurs because of the heat generated if the incorrect speed and feed rates for drilling and tapping stainless steel are applied. If the cutting speed (RPM) is too high and the feed is too

Recommended Drilling Speeds and Feeds Tel: 01827 304500

1. Higher feed and speed values should be favoured for softer materials; lower feed and speed values should be used on harder materials. 2. The above recommendations are for hole depths up to 2 drill diameters. When hole depths run 3 to 6 diameters, speeds should be reduced 10% to 35% respectively and feeds should be reduced 10% to 20%, respectively.

Drilling stainless steel 5 easy steps Cobalt drill

This is a big mistake, particularly when drilling stainless steel. Stainless steel is not the hardest of metals in its natural form, however as pointed out by Chip Lawson in his piece ‘Know How: Drilling Stainless Steel’, stainless steel will ‘work harden’ fairly quickly when heated, and one sure way to increase heat is to drill fast. Once the stainless steel is work hardened it will become very difficult to drill.

30/11/2007 Correct your speeds, feedrates, and coolant conditions, and I think you'll be able to overlook the minor difference you'll get from the tip angle or the flute pattern. The center drilling operation should be permitting your drill to center, decreasing the chance of flex or walk. The suggestion for TiN coated bits is also a good one. Final suggestion: don't use the cheap Chinese knockoffs to
