c.k tools T3035 kierrepora, halkaisija 16 mm, pituus 160 mm

The Spiral Drill bit c.k tools T3035 16mm diameter 160mm length is a long-reach twist drill designed to produce 16 mm holes in a variety of materials. With an overall length of 160 mm it provides extended access for drilling in recessed or hard-to-reach locations. The bit is compatible with standard chucks on portable electric drills and drill presses and is intended for general metalworking, woodworking and construction tasks where a longer cutting length is required.

Advantages

The drill bit combines an extended flute length with a consistent 16 mm cutting diameter to maintain hole accuracy during deep drilling. Its spiral flute geometry supports efficient chip evacuation, reducing clogging and heat build-up. The shank is machined for reliable grip in standard drill chucks, helping to minimize slippage under load. Overall construction balances rigidity and cutting clearance to suit routine maintenance and installation work.

How to use

Select a drill speed appropriate to the work material and secure the drill bit firmly in the chuck. Mark the hole position and use a center punch if drilling metal to prevent bit wandering. Begin drilling at low speed to establish the hole, then increase speed as appropriate while applying steady, even pressure. Use cutting fluid or coolant when drilling metal to extend tool life and improve chip removal. Clear chips regularly during deep drilling to maintain cutting efficiency.

Recommendations

For best results, match drill speed and feed to the material being drilled, use appropriate personal protective equipment, and ensure the drill is held steady throughout the operation. When drilling metal, apply cutting fluid periodically and withdraw the bit occasionally to clear chips and prevent overheating.
