Description
The TYROLIT STARTEC XPP+ product line represents a breakthrough in precision grinding for round tool manufacturing. Engineered for both cubic boron nitride (CBN) and diamond abrasives, STARTEC XPP+ wheels are optimized for fluting and gashing operations on HSS and tungsten carbide cutting tools. The advanced bond system and carefully designed wheel structure deliver measurable advantages: reduced grinding forces for improved process stability, or enhanced profile retention for extended dressing intervals and superior dimensional accuracy. Whether grinding carbide or steel, manufacturers can rely on STARTEC XPP+ for high stock removal, cooler cutting action, and consistently sharp edge geometry, raising productivity without sacrificing surface quality or tool precision.

Features
- Innovative Metal Bond Structure—Engineered to balance sharpness, form stability, and wheel life, providing either lower cutting forces or higher profile retention depending on application needs.
- Dual Abrasive Options (Diamond or CBN)—Diamond delivers unmatched efficiency on carbide, while CBN ensures precise results on HSS and other ferrous tool materials.
- Straight Wheel Designs (1A1, 1V1)—Optimized geometries for CNC fluting and gashing operations, offering stability and access to complex tool profiles.
- Cool Cutting Action—Minimizes thermal load on cutting tools, reducing risk of burning, edge chipping, or metallurgical damage.
- Extended Wheel Life—Lower dressing frequency reduces downtime and consumable costs, improving overall productivity.
Application
Application
- 1
Fluting operations on solid carbide end mills for high precision cutting channels.
- 2
Gashing HSS and carbide drills to produce accurate point geometry and reliable chip evacuation.
- 3
Flute and relief grinding of reamers and step tools for demanding production environments.
Recommendations
- Choose diamond for tungsten carbide and CBN for HSS to maximize grinding efficiency.
- Use adequate coolant delivery directly at the grinding zone to control heat and improve tool finish.
- Match bond hardness and grit size to the tool geometry and desired finish—coarse for heavy stock removal, fine for precision edges.
- Dress wheels with proper tools and intervals to maintain sharpness and form integrity.
- Operate within TYROLIT’s recommended speed and feed parameters for optimal results.
