Version:
- Very high feed rates and maximum performance due to optimally matched geometries and materials.
- Precise positioning of the cutter insert due to Vee insert seating and secure clamping by the centre bore.
- High concentricity when assembled.
- Shank support for optimum stability in operation.
Polished flutes.
Application:
For stationary and rotating use. For holes up to IT9 accuracy.
Note:
Further sizes up to ⌀ 50.99 mm available on request.
The insert screw must be replaced after every fifth change of cutter insert.
For process reliability when using the drill, initial pilot drilling to 1.5×D with the drill No.
231600 with the same cutter insert size and type is necessary.
The generation of a pilot hole improves process reliability.Clamp in a hydraulic chuck (such as No.
302026 size 20) for optimum radial run-out.
For optimum stability, clamp the drill so the overhang is as short as possible.
Reduce feed rates f by 10 % and v
c values by 30 %.
Warning:
Intended use- For stationary and rotating applications.
- For medium-sized bores up to IT9 accuracy, right-hand cutting.
- Only use with cooling lubricant emulsion for through-coolant.
- Carry out pilot drilling before use to increase process reliability.
- Use only with cutter insert no. 231630 – 231690, clamping screw no. 231999.
- Tighten clamping screw with torque engraved on drill.
- For work in industrial environments.
- Use only when it is technically in good condition and safe to operate.
Reasonably foreseeable misuse- The operating company must ensure that personnel who work on the product comply with the regulations and provisions together with the following instructions: National and regional regulations for safety, accident prevention and environmental protection regulations.
- No damaged products are assembled, installed or commissioned.
- The necessary protective equipment is provided.
- Use only when correctly assembled and with safety devices and guards on the machine fully operational.
