Slow helix drills
Webb6 juni 2024 · Helix Angle This is the angle between the in a side view of a twisted drill. It is also the angle of flutes about the job surface. Commonly it is 30º. This 30-degree helix angle is also known as a standard helix angle. Chisel Edge Angle It is an angle between the chisel edge and the cutting lips—an indication of lip clearance. http://www.ohiodrill.com/jobber_drills/slow_sprial

WebbThe slower spiral helix reduces the aggressiveness of the drill, allowing the operator to maintain control during hand operations. Four margins create stability in the bushing and hole, to produce close tolerance holes. We can manufacture the Double Margin Slow Spiral drill in a single diameter, drill reamer, or drill/drill ream configuration. WebbHere’s what G-Wizard would suggest for reamer speeds and feeds with a 3/16″ HSS Reamer in 300 series stainless, which was the question in the post: A 3/16″ reamer going 1″ deep in 304 stainless should run 458 rpm and 2.75 ipm feed. Chipload is 0.0015″. For comparison, here is the same cut with a 3/16″ HSS Twist Drill:
