Micro 100 3/16 inch carbide jobber drill bit bright finish

Micro 100

Micro 100 DR-187-2 3/16" Carbide 118 Deg. Jobber Drill Bit

SKU CH-EKA2-PX2BD

Carbide jobber drill bit with 118-degree point drills 3/16 inch holes in tough materials

  • 3/16" carbide drill bit for hard-material drilling
  • 118-degree conventional point starts holes cleanly
  • Bright uncoated finish resists chip welding
  • Jobber length gives standard reach and rigidity
  • Decimal size .1875 matches fractional 3/16" specification

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.
