Hole saw Dedra TCT 29 mm 1/2" for drill — bi-metal cutting blade

Dedra TCT hole saw 29 mm with a 1/2" shank is a precision cutting tool intended for making clean circular openings of 29 mm diameter. The cutting blade features a TCT (tungsten carbide tipped) edge for improved wear resistance and consistent cutting performance. It is compatible with handheld drills and drill presses and is intended for cutting through wood, plastics and similar soft to medium-density materials where an accurate 29 mm hole is required.

Advantages

The tungsten carbide tipped cutting edge delivers longer life and maintains sharpness during repetitive drilling. The 1/2" shank provides reliable clamping in standard drill chucks and reduces wobble during operation. The saw’s construction balances cutting speed with durability, offering a stable, precise bore with minimal tear-out when used with appropriate technique and support.

Suitable for

• Installing pipes and conduits that require 29 mm openings
• Routing cables and creating access points for wiring
• Drilling holes in furniture components and joinery made of wood or composite materials
• Creating mounting or inspection holes in plastic panels and similar materials

Key specifications

• Cutting diameter: 29 mm
• Shank type and size: 1/2" straight shank for standard drill chucks
• Cutting material: TCT (tungsten carbide tipped) edge
• Compatible tools: handheld electric drills and drill presses
• Intended work materials: wood, plastics and comparable soft to medium-density materials

How to use

Secure the hole saw in the drill chuck so the 1/2" shank is held firmly and centered. Mark the center point of the required 29 mm hole and, if possible, use a pilot bit or center punch to prevent slipping. Start drilling at low speed to establish the cut, then increase speed moderately while applying steady, even pressure. Support the workpiece near the cutting area to minimize tear-out and stop periodically to clear chips and check cutting progress. Allow the tool to cool if heavy cutting causes heat buildup.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. For best results in wood and plastics, back up the workpiece with scrap material to reduce exit splintering. Avoid excessive feed pressure and high speeds that can overheat the cutting edge; periodic clearing of chips will extend blade life.
