DEDRA H1241 Bi-metalová dierová píla 41 mm s HSS zubami na drevo, kov, plasty

The DEDRA H1241 stands out among hole saws by combining a 41 mm bi-metal construction with high-speed steel teeth, delivering clean, fast cuts in everything from softwood to stainless steel. Unlike single-purpose saws, this model handles wood, plywood, chipboard, plastics, plasterboard, non-ferrous metals, and even steel, making it a versatile addition to any toolbox. Its variable pitch tooth design reduces vibration and prevents clogging, while the welded body ensures long-lasting durability under demanding job-site conditions.

Highlights

• Bi-metal body with high-speed steel (HSS) teeth for superior wear resistance
• 41 mm diameter with approximately 38 mm cutting depth
• Variable pitch teeth for fast, clean cuts and reduced vibration
• Welded construction for added strength and longevity
• Compatible with standard 5/8"-18 UNF arbors (e.g., DEDRA H1201, H1202, H1203)
• Suitable for wood, plywood, chipboard, plastics, plasterboard, non-ferrous metals, steel, and stainless steel

In daily use

Whether you are installing downlights in plasterboard, drilling cable holes in wooden panels, or cutting through sheet metal, the DEDRA H1241 delivers consistent performance. The bi-metal design keeps the teeth sharp longer than standard carbon steel saws, while the variable pitch geometry minimises chatter and heat build-up. For best results, use a low speed on metal and a higher speed on wood, and always pair with a pilot drill arbor for accurate centring. The saw ejects plugs easily thanks to its open back design, saving time on repetitive tasks.
