## Long description

Ruko 204165 is a single twist drill bit designed for right-hand rotation and delivered as one piece weighing approximately 240 g. Manufactured for general drilling tasks, this tool features a Morse taper shank and a twist design suitable for creating round holes in a range of common workshop and construction materials. The bit is intended for use with standard rotary drills that accept Morse taper accessories and is engineered for drilling steel, cast steel and cast iron, as well as softer non-ferrous metals and plastics.
Advantages
The Ruko 204165 offers a robust construction with high resistance to fracture, providing reliable performance in repetitive drilling operations. Its Morse taper shank ensures secure seating in compatible drill spindles and tailstocks, improving concentricity and torque transfer compared with plain cylindrical shanks. The twist geometry supports efficient chip evacuation and consistent hole quality across a variety of materials.
Suitable for
Drilling holes in steel and alloyed steel
Working with cast iron and cast steel
Drilling non-ferrous materials such as aluminium, brass and bronze
Creating holes in plastics for assembly and maintenance
Use in workshop, maintenance and light construction tasks
Key specifications
Tool type: Twist drill bit, right-hand rotation
Diameter: 16.5 mm
Overall length: 223 mm
Shank type: Morse taper
Material compatibility: Steel, alloyed steel, cast steel, cast iron, aluminium, brass, bronze, plastic
Quantity: 1 piece
Weight (approx.): 240 g
How to use
Mount the drill bit in a drill press or rotary machine that accepts Morse taper shanks; ensure the shank seats fully and is secured according to the machine manufacturer's instructions. Select appropriate spindle speed and feed rate for the material being drilled and apply cutting fluid as required for metalworking to reduce heat and improve chip removal. Advance the bit steadily with consistent pressure; retract periodically for deep holes to clear chips and prevent clogging. After use, clean the bit and store it dry to avoid corrosion.
Usage recommendations
Use lower speeds and cutting fluid when drilling steels and cast iron to extend tool life. For non-ferrous metals and plastics, higher speeds with light feed give better surface finish—adjust parameters based on material thickness and machine rigidity.
