Serra copo KWB 598048 4,8 cm individual alumínio cobre plástico aço madeira

The KWB 598048 4.8 cm hole saw is a bi-metal cutting tool with HSS teeth alloyed with 5% cobalt, designed for drilling clean holes in a wide range of materials including aluminium, copper, plastic, plasterboard, steel, and wood. Its progressive variable tooth pitch improves chip removal and reduces binding, providing long working life and reliable performance for both professional and DIY tasks. The product is supplied on a hanging card for retail display.

Advantages

HSS bi-metal construction with 5% cobalt provides durability and wear resistance while remaining suitable for cutting softer and harder materials. Progressive variable tooth pitch ensures efficient chip evacuation and smoother cutting action. The geometry and alloying reduce friction and extend the service life of the hole saw. Compact 4.8 cm diameter makes it versatile for common drilling applications.

How to use

Install the hole saw onto a compatible arbor and secure it to the drill chuck. Choose an appropriate drill speed for the material: lower speeds for steel and castings, higher speeds for aluminium and plastics. Apply steady, even pressure and allow the tool to cut without forcing; withdraw periodically if chips accumulate. Use cutting fluid when drilling hard metals to reduce heat and prolong tool life. After cutting, clean the hole saw and remove any remaining chips before storage.

Recommendations

For best results, use a suitable arbor and pilot drill to maintain accuracy. When cutting metal, apply cutting lubricant and use lower RPM to reduce heat build-up. Wear appropriate personal protective equipment, including eye protection and gloves, and secure the workpiece before drilling.
