Descriere
Version:
Special point geometry for generating 180° flat-bottomed holes. Low radial forces even when spot drilling on faces with up to 15° slope. Flute geometry for optimum chip evacuation. With 4 guide chamfers to stabilise the drill in the hole.
Advantage:
The 180° point angle permits drilling and counterboring in a single operation.
Recommendation:
When using the solid carbide 180° drill it is absolutely essential for process reliability:
- When spot drilling on flat surfaces to drill a pilot hole 1×D using pilot drill No. 122736.
- When spot drilling on sloping surfaces up to max. 15° : reduce the feed rate f to 25% of the stated value. After spot drilling, the normal feed rate value can be used.
Note:
Flute length LC = L2 + 1.5 × DC.
