135 Degree Split Point Drill Bit

This Chicago-Latrobe jobber length drill bit features a 135 degree split point design made from high speed steel with a black oxide finish. It is engineered for general purpose drilling tasks in a workshop or job site environment. The F letter size provides a decimal equivalent of .2570 for precise hole creation.

Suited for Metal Drilling Applications

The split point geometry helps reduce walking and allows the bit to start on contact, making it suitable for users who need accurate hole placement in metal. Buyers who require coolant-through capability or bits designed for specialised non-ferrous materials should consider other options.

Questions about this item

What does the 135 degree split point do for drilling?

The 135 degree split point reduces walking and starts holes faster in metal without a centre punch.

What shank size fits a standard three-jaw chuck for this bit?

The jobber length shank matches the drill diameter of .2570 inches so it fits any chuck that accepts that size.

How do I avoid snapping the bit when drilling deep holes?

Use cutting fluid, clear chips every few seconds and keep the drill speed moderate for high speed steel.
