Walter Turning Toolholder Features Flexible Coolant Connection

Walter has introduced the Walter Turn toolholder with precision cooling and screw clamping (S…-P). Coolant is targeted on the rake face and flank face to maximize the cooling effect. In addition, rake-face cooling helps break and control chips, and double flank-face cooling directly at the cutting edge extends tool life.

Users can apply a coolant pressure from 145-2,175 psi (10-150 bar). Improved chip breaking occurs when the coolant pressure is greater than 580 psi (40 bar). Optimum coolant application increases tool life by 30-150%.

The toolholder features a flexible coolant connection: Direct coolant transfer to a VDI tool adapter (A21XX-P) or via a coolant hose set with G1/8" thread (K601). The turning toolholder provides a universal adjustment range.

The toolholder accepts CCMT3…, DCMT3… and VBMT3… (CCMT09…, DCMT11… and VBMT16…) indexable inserts. The shank dimensions are 0.75" × 0.75", 1" × 1", 20 mm × 20 mm and 25 mm × 25 mm.

Suitable applications include longitudinal turning, facing and profile turning of components with a small diameter. The Walter Turn turning toolholders are well suited for machining stainless steel, high-temperature alloys and steel (ISO M, S and P workpiece groups).

Potential benefits include the ability to cut at higher speeds and longer tool life due to flank-face cooling. The toolholder enables the production of short, manageable chips due to the rake-face cooling. Because coolant nozzles no longer need to be adjusted manually, the company says end users can experience improved machine availability and ease of operation.
