Read about our individual reamer ranges by choosing an option on the right or alternatively, download the complete Guhring reamers catalogue below: Guhring Reamers (5MB) HSS Reamers . Insufficient feed may degrade the finish and roundness of the hole and increase tool wear. Give G-Wizard a try. What gives? It’s gives you the starting hole size and good feeds and speeds for both HSS and carbide reamers. �N��F ����DA@=�l�"RY�cԆd_�8�K��(@,�]� ]���".̠���Q�ȼY{�¼U� 0000036833 00000 n

The Speeds and Feeds Calculator uses the following formulas: RPM = (12 * Surface Speed) / (PI * Tool Diameter) [revs/min], Feed Rate = RPM * Chip Load * Number of Teeth (Flutes) [in/min]. 2x the feedrate would be 4x the chip load since we’ve already doubled the spindle rpm relative to a twist drill.

Reamers are certainly not the be all and end all of hole boring, but if you’ve never used one, give it a try. In. In addition to standard coatings for milling applications (TiN, TiAlN, TiCNâ¦) IonBond offers a targeted range of high performance coatings from our Innovative Performance Coating (IPC) portfolio specifically designed for milling applications. Opinions vary on exactly what that rule of thumb ought to be for reamer speeds and feeds.

How to use: Choose a type of operation (drilling, reaming, boring, counterboring, face milling, slab milling/side milling, end milling, or turning), select your stock material, choose a material for the tool (high-speed steel or carbide), input the quantity of teeth for the tool and the diameter of the workpiece/cutter. Rather, they’re made to improve the surface finish, roundness, and hole size quickly and easily. Reamers are a fast way to finish a hole and very convenient relative to other precision approaches like boring. 0000017430 00000 n
