0.1200" / 3.05mm #31 M.A. Ford Solid Carbide Jobber Drill, 118° Bright, USA Made | 30012000

This M.A. Ford #31 solid carbide jobber-length drill bit is a USA-made precision drill for rigid drilling setups where hole accuracy, wear resistance, and clean chip flow are important. It has a 0.1200" diameter — approximately 3.05mm — with a 118° point, bright finish, fast spiral flute design, right-hand cut, and straight shank.

This M.A. Ford Twister GP Series 300 drill is also commonly described as a circuit-board drill, but it can be useful anywhere a rigid, solid carbide jobber-style drill is appropriate. Solid carbide is harder and more wear-resistant than high-speed steel, but it is also brittle, so this drill should be used in a stable drill press, CNC machine, or precision fixture with minimal runout and no side loading.

Typical Applications

• Precision drilling in rigid setups
• Circuit-board style drilling and other controlled small-hole applications
• Controlled drilling in plastics, wood, aluminum, brass, composites, cast iron, and suitable metals
• Drill press, CNC, fixture-based, and other stable drilling applications
• Applications where a USA-made M.A. Ford solid carbide drill is preferred

Benefits

• Solid carbide construction provides high hardness, rigidity, and wear resistance
• Bright finish provides a smooth tool surface for chip flow in suitable materials
• Fast spiral flute design helps move chips out of the hole efficiently
• 35° helix angle supports chip evacuation in suitable drilling applications
• USA-made M.A. Ford Twister GP drill for precision carbide drilling
