Carbide Counterbore for Our Extra Small Corby .189" Cutting with .125" Pilot

 Ean: 0616639448276   |    PartNumber: DTSB-CCT-CB-147379   |   Asin: B07JJN58X5

The major diameter is slightly oversize to compensate for the material being relieved to shrink back. When drilling G10 or Micarta (or other fabric phenolic) the material shrinks back slightly. In other words if you drill a .125" diameter hole in canvas micarta, it is going to finish around .123" in actual diameter. We had these counterbores sized to take into account the hole shrinking in size. These are carbide so they should last a very long time if you are drilling wood, g10 or phenolic. They will also relieve metal like stainless or titanium but expect them to wear faster. Like all drills, consider these a consumable. Eventually, they will wear enough they have to be replaced. Since they are carbide, they will snap if subjected to side loads where a regular drill bit could handle it. Secure your work piece and keep your drilling straight up and down. If you snap one of these, you own both pieces. To use these: Locate and drill the minor diameter (pilot) holes in your handle material. Insert the counterbore and align the holes and secure your work piece or hold on tight so you don't bend and break the carbide counterbore. Drill just deep enough for the major diameter to hold the scale in place after your grind the excess corby bolt head away. I eyeball this but you can also set up a gauge and countersink to your exact depth. If you are doing several, use the drill stop on your drill press (finally a use for that!) to set the depth of the counterbore and drill all of them at once. The drill stops occasionally move so check your work frequently in case it slips and goes too deep. NOTE: We have several sizes of counterbores pictured for clarity of illustration. You are ordering one counterbore of the size shown above.

Features

  • Major Diameter (shoulder): .189/190"
  • Minor Diameter (pilot): .125
  • Material: Carbide
  • Type: One piece - non-removable pilot
  • Fits EXTRA SMALL Corby bolts that are .187 Shoulder Diameter with .125 shaft Diameter

Drill America qualtech decor series aircraft counter bore. Counter boring is the enlargement of a portion of a hole that has previously been formed. If the counter bored portion is shallow (1/inches or less), the operation is usually known as spot-facing; for example, a flat Seat for a bolt head or nut. If, on the other hand, the hole is enlarged to a considerable depth, it is designated as counter boring. This counter bore is made of two-piece construction, having an integral shank and counter bore-cutter, and a pilot that is interchangeable, which provides flexibility in the use of the tool. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Round shanks allow use with a wide variety of tool holding systems.
