Cleveland 1/2" Carbide Jobber Drill Bit
This Cleveland C47718 jobber length drill bit is manufactured from carbide for high wear resistance in demanding applications. The 1/2 inch fractional size with a .5000 decimal equivalent suits precision drilling tasks in tough materials. Its 118 degree four facet point design promotes accurate centring and reduced thrust during operation. The bright uncoated finish is intended for general purpose use without coolant through the tool.
Integration into workshop setups
The jobber length format fits standard drill chucks and collets used in bench or handheld machines. Carbide construction allows higher cutting speeds in hardened steels or abrasive alloys where high speed steel would dull quickly. The 118 degree point angle is a general purpose geometry not optimised for specialised deep hole or high feed strategies. Buyers needing coolant through capability or coated performance for extended tool life should select a different specification.
Highlights
- Carbide construction resists wear on hard materials
- 118-degree point angle centres accurately on contact
- Four-facet point design reduces thrust and walking
- Bright uncoated finish suits general-purpose drilling

Questions about this item
How long will the 118-degree 4-facet carbide point hold its edge in steel before it needs resharpening?
The carbide tip keeps a sharp edge far longer than high-speed steel, but exact drill-life in steel varies with feed rate, coolant use and material hardness.
Does the bright uncoated carbide body run hotter or need more cutting fluid than a coated bit during all-day drilling?
Without a coating the flute runs warmer and welds chips more easily, so steady flood coolant or frequent peck cycles are needed to control heat on long jobs.
