Hole Saw Dedra TCT 68mm 5/8" – universal cutting tool, model 08X068

Dedra TCT 68mm 5/8" hole saw (model 08X068) is a circular cutting tool designed to create clean 68 mm diameter openings. Fitted with tungsten carbide tipped (TCT) teeth and a 5/8" arbor connection, this hole saw is intended for cutting through wood, plastics and thin metals where a precise round hole is required. The construction combines a hardened cutting edge with a body designed for chip removal and stable cutting performance.

Advantages

The tungsten carbide tipped teeth provide increased wear resistance and maintain sharpness longer than standard bi-metal teeth, enabling consistent cutting quality over multiple uses. The 5/8" arbor interface ensures compatibility with common drill arbors and drivers. Its 68 mm diameter meets standard sizing needs for many plumbing and electrical installations, offering repeatable hole diameter and reduced need for finishing. The saw geometry and chip clearance reduce binding and heat build-up during typical drilling operations.

Suitable for

• Cutting round openings in soft and hardwoods
• Making holes in plastic and PVC components
• Creating pass-throughs in thin sheet metal and metal ducts
• Plumbing and electrical installations requiring precise circular holes

Key specifications

• Cutting diameter: 68 mm
• Tooth type: Tungsten carbide tipped (TCT)
• Arbor connection: 5/8"
• Intended materials: Wood, plastics, thin metals
• Design: Circular saw body with chip clearance slots

How to use

Secure the hole saw onto a compatible 5/8" arbor and tighten according to the arbor manufacturer's instructions. Mark the center of the intended hole and, if available, use a pilot bit to establish a starting point. Begin drilling at moderate speed with steady pressure, allowing the TCT teeth to cut without forcing the tool. Periodically withdraw the saw to clear chips and reduce heat build-up, especially when cutting plastics or metals. After cutting, deburr the hole edges as needed for a clean finish.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For thin metals, use cutting lubricant and lower speed to reduce heat and prolong tooth life. Avoid excessive side loading and do not use the tool in rotary hammer mode. Inspect the TCT teeth regularly and replace the saw if teeth are damaged or excessively worn.
