Union Materials Tech Spec
💡 Specialty Tooling: For custom single-tip brazed PCD groovers (1.5mm & 1.65mm width), our standard substrate is SPD2000. Use our RFQ portal on the home page for drawing submissions.
Optimal Grade Recommendation
SBC2000 or TX920 / TX520
Cutting Speed (Vc)
180 – 350 m/min (600 – 1,150 SFM)
Feed Rate (fn)
0.08 – 0.25 mm/rev (0.003 – 0.010 IPR)
Depth of Cut (ap)
0.20 – 2.00 mm (0.008 – 0.080 in)
Edge Prep
Honed (0.02 – 0.03 mm)
• TX520 is the standard cermet choice delivering brilliant surface finish.
• SBC2000 (Brazed Coated pCBN) is recommended when hardness exceeds HRC 45 or when extreme tool life is required.
