The helix angle is an additional tool geometry consideration. Traditionally when machining aluminum a tool with a high helix angle has been used. A high helix angle lifts the chip away from the part more quickly, but increases the friction and heat generated as a result of the cutting action. A high helix angle is typically used on a tool with ...Get Price

How to Machine Titanium Like a Pro – Make It From Metal
Usually for steel the teeth will be as a slight helix, but for titanium the angle of the teeth is often between 3060 degrees from the tool axis. This results in a smoother cutting action that more so shears the material away instead of whalloping it off. You can really hear the difference between a low helix and a high helix cutter.Get Price
Why 118? Why 135? (Drill angle) Practical Machinist
Apr 23, 2016· To these helix angles we also must add proper relief for clearance. Relief angles of from four to six degrees depending on the material being cut added to the helix angle make up the total cutting lip clearance.
