High-hardness tungsten carbide micro-roller wheel core - instant precision-scoring utility
glides across flat glass, mirrored panes, and mosaic sheets to scribe a continuous, micro-fine fracture line, ensuring clean, predictable breaks with minimal edge chipping
Hardened alloy steel head & threaded internal oil-reservoir barrel matrix - versatile wear-and-pressure defense
endures firm downward hand pressure, heavy glass workshop duty, and repeated scoring cycles without dulling the cutting wheel edge, stripping screw threads, or leaking internal cutting fluid
Automatic spring-dosed oil dispensing & ball-end tapping head design - total glass-and-fracture protection
lubricates the roller wheel continuously during scores to prevent surface heat fractures and jagged edges, while the rounded brass tail delivers controlled shock-taps to separate cuts without shattering surrounding glass
Ergonomic cross-knurled non-slip metal pencil grip - convenient score-and-snap setup
fits naturally between the fingers like a fine drafting pen for pinpoint line accuracy on straight edges or tight curves, refilling cleanly through the top screw cap with any standard cutting oil
Architectural glazing & stained-glass artisan craft framework - effortless clean-break system
cuts picture frame glass, stained-glass suncatchers, mirrored wall tiles, greenhouse glazing, and custom window replacements across home framing studios, stained-glass workshops, and professional glass glazier benches
