Jobber Drill Bit .3480 Size S
This Chicago-Latrobe jobber drill bit is manufactured from high speed steel with a TiN coating for extended wear resistance. The 135 degree split point design reduces walking and provides accurate hole starts without a centre punch. It suits general-purpose drilling in metal, wood and plastic for trade and DIY users.
Straight Shank Fits Standard Chucks
The straight shank installs directly into any standard three-jaw drill chuck without adapters or special tooling. Tighten the chuck securely to prevent slippage under load. The split point geometry can chip if excessive side pressure is applied during deep holes or when drilling hardened materials beyond the bit's capacity.

Questions about this item
How can I confirm the 135-degree split point is cutting correctly after I start drilling?
The bit should self-centre without wandering and produce short, curled chips in steel when the 135-degree split point engages properly.
Does the box include any cutting fluid or only the TiN-coated HSS bit?
Only the single jobber-length drill bit is supplied; cutting fluid or lubricant must be purchased separately.
