The Draper Diamond Glass Cutter is a hand-held scoring tool designed to make controlled, repeatable scores in sheet glass for subsequent snapping. Its primary use is for glass cutting tasks in glazing, picture framing, stained glass work and light fabrication where accurate straight or curved breaks are required rather than power sawing. The cutter produces a fine score line using a diamond-tipped wheel so the glass can be separated cleanly without chipping.

The cutting element is a synthetic diamond tip mounted in a hardened steel head; the body is manufactured from hardened carbon steel (commonly EN8 / 1045-grade equivalent) with a corrosion-resistant chrome-plated finish and an ergonomic PVC grip to aid control. The head is set at an oblique angle to the handle to allow comfortable scoring along flat glass. This is a manual scoring tool so thread type, head-thread or drive type are not applicable. Replacement diamond wheels are available for this model to maintain cutting performance.

While glass cutters are not subject to a single bespoke product standard, this Draper tool is manufactured to recognised DIN, ISO and BS hand-tool standards and under an ISO 9001 quality system, ensuring dimensional consistency and safe manufacture. The diamond tip delivers the hardness necessary to score annealed and float glass reliably (diamond = 10 on the Mohs scale) and will retain a serviceable life far longer than carbide-only wheels when used correctly and kept lubricated.

Typical applications include domestic and commercial glazing, stained glass and leadlight work, picture framer workshops, glazing contractors replacing small panes, and laboratory or educational glasswork where controlled manual scoring is preferred. The cutter accepts cutting oil or can be used dry for short runs; oil helps extend wheel life and improves score quality on thicker or harder glass.

Key benefits include precision scoring from the diamond tip, long tip life, rust-resistant plated body that prolongs tool life in workshop environments, and a comfortable grip for consistent control. Duchy Fasteners stocks this Draper diamond cutter in single and multipack options, together with replacement wheels and alternative Draper glass cutters (pistol-grip and oil-fed types) to suit different glass thicknesses and workshop requirements.
