About this product
What This Product Is and How It Works
The DELI Holesaw TCT 20 mm DHTCT020‑E1 is a hollow‑cup drilling accessory with carbide‑tipped cutting edges. Hole saws cut a circular groove into the workpiece, allowing the central core (or slug) to be removed while leaving a clean round hole. The TCT (tungsten carbide tipped) teeth offer enhanced hardness and wear resistance compared with plain steel teeth.
To use, the holesaw is mounted on an appropriate arbor or mandrel fitted into a drill. The pilot bit helps centre the saw and stabilises the cut, while the carbide‑tipped teeth engage the work surface and progressively remove material as the drill rotates.
Material Quality, Durability and Environmental Performance
The carbide‑tipped teeth provide higher abrasion resistance and longer life than bi‑metal hole saws, especially in harder materials. TCT cutting edges perform well in wood, plastics, non‑ferrous metals like aluminium, and some stone or tile substrates, depending on specific TCT grade and tooth geometry.
The sturdy body combined with carbide tips resists wear under demanding use, supporting repeated hole‑cutting tasks in workshop and site conditions where moderate dust and heat build‑up occur.
Installation, Handling and Compatibility
Install the holesaw on a compatible arbor and secure in a standard electric or cordless drill chuck. Confirm the pilot bit is centred and rotate the drill at moderate speed to start the cut. Use firm, steady feed pressure—avoid excessive force that can tilt the saw or overheat the cutting edges.
Holesaws are typically used in rotary mode; hammer action is not recommended as it can damage the cutting teeth or pilot drill. Wear appropriate personal protective equipment including eye protection and gloves.
Typical Applications in Kenya
This holesaw is used to create round openings for installations and fittings in construction and renovation projects. Typical uses include drilling holes for conduit entry, pipe penetrations, cable runs, switchboxes, fitting brackets, or penetrations in panel materials.
It is suitable for fundis, electricians, carpenters, and general tradespeople. For related drill accessories and tooling, browse the full range in our Shop or explore the Power Tool Accessories Category.
