Serra copo bimetal DEDRA H1229 29 mm – dentes HSS para cortes limpos em madeira, metal, plástico

With a 29 mm cutting diameter and bi-metal construction, this DEDRA H1229 hole saw delivers clean, precise holes in wood, plastics, plasterboard, non-ferrous metals, steel, and even stainless steel. The high-speed steel (HSS) tooth tips are welded to a tough alloy steel body, giving you a tool that resists wear and heat while maintaining sharpness through repeated use.

Overview

The DEDRA H1229 is a single hole saw designed for general-purpose drilling. It features variable tooth pitch to reduce vibration and improve cutting efficiency across different materials. The saw body is made from alloy steel for strength, while the teeth are made from HSS for durability. It has a maximum cutting depth of 38 mm, allowing you to cut through thicker workpieces. This hole saw requires a compatible arbor and pilot drill, which are sold separately.

What stands out

• Bi-metal construction: HSS teeth on an alloy steel body for long life and high wear resistance.
• Variable tooth pitch: Reduces chatter and provides smoother cutting in a variety of materials.
• Versatile material compatibility: Works on wood, plastics, plasterboard, non-ferrous metals, steel, and stainless steel.
• 29 mm diameter: Ideal for creating holes for pipes, cables, and hardware.
• 38 mm max cutting depth: Suitable for many standard applications.
