Micro 100 3/64" Carbide Jobber Drill Bit
This Micro 100 drill bit uses solid carbide construction for drilling hardened materials and abrasive alloys. The 118-degree conventional point starts cleanly without a pilot hole. Bright uncoated finish suits general-purpose machining. Tolerance of +.0000/-0.0005 inches ensures repeatable hole size in CNC and manual operations.
Capacity and headroom for small-diameter precision
At 3/64 inch diameter the bit handles tight-tolerance holes in tool steel, stainless steel and high-silicon aluminium. Carbide substrate resists wear far longer than high-speed steel in these materials. The jobber-length flute clears chips in depths up to several diameters. In softer plastics or wood the aggressive point can grab; reduce feed or choose a sharper angle for those jobs.
Upgrade from HSS jobbers when tool life matters
Shops replacing worn high-speed steel bits gain longer intervals between changes and tighter size control. The jump pays off in batch runs where re-sharpening downtime hurts throughput. For one-off holes in mild steel or non-ferrous metals a standard HSS bit remains adequate and less brittle.

Questions about this item
Will the 3/64 inch carbide jobber bit fit a standard 1/4 inch drill chuck I already own?
Yes, the 3/64 inch shank is well within the 1/4 inch capacity of a standard chuck, so it will clamp securely in your existing drill.
How can I confirm the 118 degree point angle is cutting correctly after I start drilling?
The bit should self-centre immediately, produce clean chips without wandering, and leave a round hole within the +0.0000/-0.0005 inch tolerance.
Does the package include any cutting fluid or a storage case, or must I buy them separately?
The box contains only the single carbide drill bit; cutting fluid and a storage case are not included and must be purchased separately.
