Precise 3/16" carbide jobber bit
This carbide drill bit measures 3/16 inch with a 118-degree conventional point for accurate hole-making in demanding materials. The bright uncoated finish preserves the substrate's hardness and sharpness. It is built for professional workshops that require consistent performance on tough alloys.
Rigid carbide construction for daily use
Solid carbide eliminates flex and holds tight tolerances through repeated drilling cycles. The jobber-length flute clears chips efficiently in through-hole and deep-hole applications. A conventional point geometry starts cleanly without walking on flat or curved surfaces.
Upgrade from high-speed steel in abrasive metals
Shops switching from HSS gain longer tool life when drilling hardened steels, cast iron or composites. The jump pays off when hole counts rise and regrind intervals stretch beyond what coated HSS can sustain. It is not suited for soft aluminium or hand-held drilling without rigid guidance.

Questions about this item
What does the 118-degree point angle mean for drilling?
The 118-degree conventional point is a general-purpose geometry that centres well in steel, aluminium and plastics without a pilot hole.
What shank size fits this 3/16-inch jobber bit?
The shank matches the 3/16-inch drill diameter, so it clamps directly in any 3/16-inch or larger three-jaw chuck.
How do I avoid breaking the carbide tip on first use?
Start at low RPM with steady feed pressure; carbide is brittle and snaps if the bit grabs or wanders before the point seats.
