Get Up To Speed!
Increase Your Drilling Feed Rates By Up To 50% With Sandmeyer E-Z Drill Stainless Steel Plate

Sandmeyer Steel Company produces a free-machining version of types 304, 304H, 304L, 316, and 316L Stainless Steel Plate. The improved machinability of these steels is the result of carefully controlled chemical analysis and improved melting practices that reduce the size of non-metallic inclusions that are common in air-melted stainless steel.

We tested our drilling operations on 1/2", 3/4", 1", 1-1/4" and 1-1/2" oil hole drilling.

The optimum performance came at 50 SFM on each drill. This is basically the same RPM range we normally run on each size. However, we were able to increase feed rates and penetration rates significantly on each size.
