Hole saw Dedra TCT 19 mm with 1/2" shank — Dedra 08X019

Dedra Otwornica uniwersalna TCT 19mm 1/2'' is a universal TCT hole saw with a 19 mm cutting diameter and a 1/2'' shank. It features a tungsten carbide-tipped cutting edge designed to produce precise round holes in a range of compatible materials. The tool is intended for use with drills that accept a 1/2'' shank and is suitable for tasks requiring a clean, accurate bore where a durable, wear-resistant cutter is beneficial.

Advantages

The TCT construction combines a steel body with tungsten carbide teeth to provide increased cutting life and resistance to abrasion compared with standard high-speed steel cutters. The 19 mm diameter offers a common size for conduit, pipe and fixture penetrations while the 1/2'' shank ensures compatibility with many hand and bench drills. The tool maintains hole roundness and edge quality during repeated use and performs consistently in applications that require a sharp, durable cutting edge.

Suitable for

• Drilling holes for plumbing pipes and fittings
• Creating openings for electrical conduits and cable glands
• Installing fixtures, fasteners and mounting hardware
• General workshop drilling where a carbide-tipped saw is preferred

Key specifications

• Cutting diameter: 19 mm
• Shank type: 1/2'' compatible
• Cutting material: Tungsten carbide-tipped (TCT) teeth
• Body material: Heat-treated steel
• Intended use: Hole sawing for round penetrations

How to use

Secure the hole saw to a compatible arbor or directly into a drill chuck with a 1/2'' capacity, ensuring the connection is tight and concentric. Mark the drilling position, start drilling at low speed to establish the pilot contact if using a pilot bit, then increase speed moderately while applying steady, even pressure. Periodically withdraw the cutter to clear chips and prevent overheating; use cutting fluid or coolant when working on metals to extend tool life. After completing the cut, reduce drill speed before removing the tool and clean the teeth of debris.

For best results, match drill speed and feed to the material being cut: lower speeds for metals and higher speeds for softer materials. Use light coolant for metal cutting, keep the tool steady and replace the cutter when teeth become worn to maintain hole quality.
