Reaming single carbide disc Widia

Widia developed the single carbide disc reamers in the Top Ream platform, for excellent reaming and hole finishing covering hole diameters up to 42 mm, with three TRF shank-styles starting at 14 mm and the TRM modular tool from 20 mm and up. Alternative to boring tools and conventional brazed carbide-tipped reamers, the Widia reaming solution Top Ream uses a single carbide disc and brazed joint, instead of four to eight (or more) individually brazed carbide tips, providing a strong connection that is virtually immune to thermal effects during machining operations.

In addition, carbide always provide a good center to locate on, ensuring a minimum of four ‘like new’ accurate regrinds, and also the single piece of carbide is inherently more stable and resistant to vibration. The through-hole style has an 18-degree left hand spiral, doing a great job of pushing the chip forward. The Top Ream TRM series’ mounting mechanism makes simultaneous contact on the cutting head’s face and taper, so that the reamer head pops out by simply twisting the locking screws, with no need for head to body orientation, providing a strong, vibration-free and precise reamer interface, with virtually zero run out. The reaming tools size range covers the lion’s share of application requests from customers, and offers a wide variety of custom geometries, diameters and edge preps, all available in three weeks or less.
