13 mm Split-Point Jobber Bit
The Chicago-Latrobe 45905 is a 13 mm high-speed steel jobber drill bit with a 135 degree split point. Black oxide finish reduces friction and resists corrosion during general-purpose drilling. The 151.00 mm overall length suits standard chuck capacities.
For Metric Drilling in Steel and Alloys
This bit suits workshops and maintenance crews drilling 13 mm holes in ferrous metals where a split point prevents walking. It is not for buyers who need coolant-through capability or a different point angle for specialised materials. Non-metric projects should look at fractional-size alternatives.
Fits Standard Drill Chucks
The straight shank seats in any three-jaw chuck that accepts 13 mm tooling, so no special holders are required. The split point centres the cut immediately, freeing the operator from centre-punching every hole. Black oxide coating extends bit life between resharpening intervals.

Questions about this item
What chuck capacity does my drill need for the 13 mm shank?
A 13 mm or larger chuck is required to hold the 13 mm diameter shank securely.
Will the 135 degree split point start cleanly on the mild steel I usually drill with older bits?
The 135 degree split point reduces walking and requires less thrust than standard 118 degree points on mild steel.
How can I confirm the bit is cutting correctly once installed?
Expect short, curled chips and a smooth hole diameter close to 0.5118 inch when drilling at proper speed and feed.
