Questions about this item
How does the 118° point angle affect drilling performance?
The 118° conventional point is a general-purpose geometry that centres well on steel, cast iron and non-ferrous metals without a pilot hole.
What does the bright finish mean for tool life and chip flow?
Bright finish means the flute is uncoated; it resists galling in soft materials and allows easy resharpening, but offers no heat or wear barrier in abrasive alloys.
