The Cimco 20 7435 hole saw is a single-piece cutting tool with a 3.5 cm diameter designed for creating clean circular holes in a variety of materials. It is suitable for work on cast iron, copper, stainless steel and wood, providing consistent cutting performance for both professional tradespeople and DIY users. The compact cylindrical design and durable cutting edge make it a practical choice when precision and reliable results are required.

Advantages

The hole saw offers a robust single-piece construction that reduces the risk of breakage at connection points and simplifies handling during cutting. Its tooth geometry and material compatibility support effective chip removal and steady cutting in metal and wood, while the moderate diameter provides a balance between control and material removal rate. The tool’s design helps maintain hole roundness and dimensional accuracy over repeated use.

How to use

Select a compatible arbor and pilot drill suited to the hole saw and the material being cut. Secure the workpiece and mark the hole position. Start drilling at low speed to establish the pilot and then increase speed as appropriate for the material; maintain steady pressure and allow the tool to cut without forcing. Periodically withdraw the hole saw to clear chips and reduce heat buildup. After completing the cut, deburr the hole edges as needed.

Recommendations

Use cutting fluid when working with metals to improve chip evacuation and reduce heat. For thicker or harder metals, operate at lower speeds and make progressive cuts rather than forcing the tool. Always follow safety precautions: wear eye protection, clamp workpieces securely and use the correct arbor and pilot for stable operation.
