Cutting Blades & Scoring Wheels
Tungsten carbide cutting blades and diamond-tipped scoring wheels for glass cutting tables. The first point of contact in every glass processing operation — where quality begins.
How It Works
Four stages from blade selection to clean breakout — the engineering behind every score line.
Why Hanwin Blades
Every blade laser-inspected, every edge geometry verified. Quality you can see at the score line.
Vacuum-Sintered Carbide
HV 1400–1600 hardness — 30% harder than standard HSS blades. Maintains edge geometry 3× longer.
25° Precision Edge
Optimized angle concentrates scoring force for clean fracture lines. Reduces breakout force by 30–40%.
Laser-Inspected Quality
Every blade is laser-inspected for edge geometry before packaging. Zero defects guaranteed.
Tool-Free Replacement
5–10 minute swap with no special tools. Pre-labeled orientation marks ensure correct installation.
30–40% Reduced Breakout Force
The 25° precision edge angle concentrates scoring force for clean fracture lines, reducing breakout force and eliminating edge chipping.
Technical Specs
Vacuum-sintered carbide precision-ground to exact tolerances for consistent score line quality.
How It Compares
Cutting blades lead in precision and cost efficiency — the first point of contact that determines quality downstream.
Cutting blades score highest in Precision (95) and Cost Efficiency (85) — the critical first step that determines the quality of every downstream operation.
Where It Excels
From manual cutting stations to high-speed CNC centers — the right blade for every cutting operation.
Float Glass Cutting
Cutting Tables
Float glass cutting tables require blades that produce clean score lines with minimal breakout force. Hanwin's vacuum-sintered carbide blades maintain edge geometry across thousands of cuts, ensuring consistent glass quality from the first cut to the last.

Keep Them Sharp
Five essential practices to maximize blade life and maintain consistent score line quality.
Check blade edge under magnification at the start of each shift. Even small chips cause score line defects that compound through downstream processing.
Wipe blade with isopropyl alcohol after each production run. Glass dust accumulation on the edge degrades scoring quality over time.
Don't wait for complete failure. Replace when scoring force increases by more than 15% — continuing with a dull blade damages glass and wastes time.
Always store spare blades in original protective caps. A dropped blade has microscopic edge damage that causes score line defects.
Scoring wheel pressure must be recalibrated when changing glass thickness or type. Incorrect pressure causes either shallow scores (difficult breakout) or deep scores (edge chipping).
Common Questions
Everything you need to know about cutting blades and scoring wheels.
Depends on glass type and volume. For annealed float glass: every 800–1,200 cuts. For tempered glass: every 400–600 cuts (harder surface accelerates wear). Monitor scoring force — when it increases 15% above baseline, replace.
Carbide wheels are cost-effective for standard float glass. Diamond-tipped wheels cost 3–4× more but last 3–5× longer and produce cleaner scores on hard-coated or tempered glass. For high-volume operations, diamond pays for itself within 2–3 months.
Technically yes, but not recommended. Resharpening changes the edge geometry and removes the factory finish. A resharpened blade produces score lines 20–30% worse than a new blade. At Hanwin's pricing, replacement is more cost-effective than resharpening.
Three main causes: (1) Incorrect scoring pressure — too much pressure accelerates edge wear, (2) Cutting tempered glass with an annealed-glass blade — the harder surface destroys the edge, (3) Dropping or bumping the blade — microscopic damage propagates under scoring loads.
