Cylindrical reamers with spiral flutes

Hand cylindrical reamer for final hole machining: after drilling with a small allowance it removes a thin metal layer and brings the hole to exact size with a smooth wall — for pins, bushes, shafts and precision bolts.

Application:
- calibrating holes for cylindrical pins and bushes
- fitting holes during assembly and repair of units
- machining structural steel, cast iron, copper, brass and aluminium

Features:
- high-speed steel HSS
- spiral flutes cut smoothly, without vibration, and clear chips; suitable for holes with a keyway or cross hole where a straight-flute reamer jams
- long lead taper enters the hole easily and centres the tool
- shank with square for tap wrench

Application procedure:
1) drill the hole with reaming allowance
2) insert the reamer lead taper into the hole, hold the wrench coaxial
3) rotate only clockwise, smoothly, with lubricant
4) withdraw the reamer while still rotating the same way — reverse rotation dulls cutting edges
