Masonry Chisels Gedore 8769920

Gedore 8769920 masonry chisels are made from chrome-molybdenum-vanadium air-hardening steel (45CrMoV7) and are fully hardened and tempered along their length. The striking heads receive inductive tempering, while the working edges are polished and coated with a clear varnish. These chisels are intended for precise shaping and cutting of bricks and stones and are supplied in a non-standardised form.

Advantages

The construction from 45CrMoV7 steel with full-length hardening and tempering ensures high wear resistance and edge retention. Inductively tempered striking heads increase durability under repeated hammer blows. Polished working edges and clear varnish reduce corrosion and provide a consistent cutting surface. At 710 g, the tool balances control and impact force for manual masonry tasks.

Suitable for

• Shaping and cutting bricks
• Chiselling and splitting masonry units

How to use

Position the chisel along the intended cut or shaping line and hold it firmly at the handle. Strike the chisel head with a suitable hammer or club hammer, applying controlled blows to remove material gradually. For deeper cuts, make a series of shallow passes rather than attempting large single blows. Keep the chisel steady and aligned to maintain a straight cut. After use, wipe the tool clean and store it in a dry place.

Usage recommendations

Use appropriate eye and hand protection when working with masonry chisels. Match the hammer type and weight to the chisel and task to avoid damage to the striking head. Regularly inspect the edge and striking face for deformation; regrind or re-temper only using proper tooling and procedures.
