WIDIA Extra Length Drill, Series: TOP DRILL TDD108, E Drill Size – Letter, 0.25 in Drill Size – Decimal Inch, 267 mm Overall Length, 30XD Cutting Depth, 2 Flutes, Spiral Flute, 214 mm Flute Length, 7 mm Dia x 38 mm L Shank, Z Shank, 132 deg Point, TDS Point, Right Hand Cutting, Solid Carbide Cutting Edge, Solid Carbide, PVD TiN/TiAlN Coated, Applicable Materials: Cast Iron and Steel, Yes Through Coolant (Yes/No)
- 132 deg TDS point geometry low thrust, excellent centering capabilities and easy to regrind
- 30 deg helix with optimized flute profile reduces risk of chip jamming and catastrophic failure
- 4-margin lands improves hole straightness and improves hole alignment when drilling through cross holes and inclined exits
- Highly polished surfaces reduction of friction in the chip flute and on the lands, resulting in superior chip evacuation and shorter drilling time through omission reversing cycles
- WU20PD grade with a multi-layered PVD TiN-TiAlN coating, a high quality submicron carbide substrate and a state of the art surface condition, this grade gives the highest level of wear resistance at high cutting speeds
- A state of the art surface condition enables superior chip evacuation even when MQL is applied
