43/64" HSS Jobber Drill Bit
This Drill America D/AN43/64 bit is a high-speed steel jobber-length drill with a black oxide surface treatment. It is built for general-purpose drilling in metal, wood and plastic where a 43/64 inch hole is required. The jobber profile provides standard flute and overall lengths for everyday workshop use.
Capacity and headroom
The bit drills a precise 43/64 inch diameter, with a decimal equivalent of .6719. Its flute length of 5-5/8 inches and overall length of 7-5/8 inches give ample reach for through-holes in thick stock. It is not suited for very deep holes beyond the flute length or for hardened steels that demand cobalt or carbide tooling.

Questions about this item
Will this 43/64" HSS bit fit the chuck of an older 1/2" capacity drill press?
The 43/64" diameter equals 0.6719", which exceeds a standard 1/2" chuck capacity, so it will not fit that older press.
How can I confirm the bit is cutting correctly after I start drilling?
A properly cutting 43/64" HSS bit produces continuous, straw-coloured chips and advances smoothly without excessive heat or chatter.
