Countersink Selection Guide for Sheet Metal Factories
Countersink solutions tailored for the Sheet Metal Processing industry, solving your machining pain points
⚠️ Common Sheet Metal Processing Pain Points
Burrs on Stainless Steel Chamfers
Standard tools lack hardness, stainless steel cutting produces burrs requiring secondary deburring
Short Tool Life
Frequent tool changes in mass production reduce efficiency and increase tooling costs
Uneven Countersunk Holes
Inaccurate tool angles prevent screw heads from seating fully, affecting assembly quality
✅ Lihao Technology Solutions
Cobalt HSS Material
HRC67 hardness with toughness - no chipping on stainless steel, smooth burr-free surface
TiAlN Composite Coating
0.15 friction coefficient, no chip welding, smooth chip evacuation, 40% higher efficiency
Precision Grinding
Angle tolerance +/-0.1 degrees, flat countersunk holes, screw heads fully seated
