Hole-Finishing Tools Designed For Fine Surface Finishes
The company’s line of hole-finishing tools includes Burraway and Burr-Off mechanical deburring tools for controlled edge break or burr removal on both sides of holes in one pass. Shefcut precision reaming and boring tools which are designed for accurate size, fine finish and superior hole geometry are also available. Tools for burnishing include multi-roll, single-roll, and diamond burnishing tools, which are said to provide for accurate sizing, fine finishing, and work-hardening of bores and shafts in seconds.

Cobalt HSS Drill For Deep-Hole Drilling
For deep-hole drilling, the company offers the Helios 15D and 20D cobalt HSS drills. The drills can process deep holes without the use of an internal coolant supply and without pecking. The flute design improves chip evacuation, making it feasible to drill as much as 20 × D without pecking.

Tapping Holder Improves Thread Quality And Tap Life
The Mega Synchro tapping holder compensates for synchronization error during rigid tapping by reducing the thrust load to both the tap and workpiece, improving thread quality and tap life. This is facilitated through a mechanism that absorbs the pitch difference between the tap and synchronous spindle. Capable of supplying coolant through slits to the tap periphery, the holder is available in various lengths and spindle interfaces to suit any company’s needs.

The Conform-A-Chuck and Conform-A-Arbor workholding solutions are designed to adapt to an out-of-round OD or ID and securely grip that diameter to enable boring, honing, grinding or other machining operations without changing the original free-state shape of the part. These workholding solutions are suited for the machining of thin-walled parts such as automotive smog control air pump rotors, gas turbine parts, thin-wall tubing and cylinder liners for diesel engines. The Conform-A products rely upon a plastic material called Hydra-Fibre.
