Chicago-Latrobe 70229 Drill Bit
This 29/64 inch jobber length drill bit is made from high speed steel with a titanium nitride coating. The 118 degree conventional point angle suits general purpose drilling across a range of materials. It is a fractional inch size with a decimal equivalent of .4531 inch.
Suited for general purpose drilling tasks
Machinists and maintenance technicians needing a standard fractional size for medium diameter holes will find this bit appropriate. The high speed steel construction handles typical steel and iron workpieces. Buyers who need coolant through capability or a different point geometry for specialised materials should look at other options.
29/64 inch fractional size decides fit
The exact 29/64 inch diameter determines whether this bit matches the hole requirement for tapping, clearance or pilot drilling. Verify the fractional size against the drawing or specification before purchase. No other specification overrides this dimensional requirement.

Questions about this item
Will a 29/64 in jobber bit fit my standard drill chuck?
The 29/64 in fractional inch shank fits standard three-jaw chucks that accept up to 1/2 in capacity.
How do I avoid breaking the 118 degree point when starting a hole?
Use a centre punch mark and low speed with steady pressure so the conventional point engages cleanly without wandering.
When should I replace the TiN coated high speed steel bit?
Replace it when the cutting lips show visible wear or the gold TiN coating has worn away, causing slower cutting and excess heat.
