Tap and Die Set

Our experience in the marketplace has given us a wide knowledge of all special geometries that are needed. Therefore we are very happy to make special forms, since we are a very flexible company and our production is set up for us to make special inserts easily. As this is a new release we will be designing many more different standard threading inserts. Contact your local distributor to make sure we update with your specific geometries first.

A center drill is a good choice on more dense metals, but it would not be practical for a softer metal. A spot drill can do the job just as efficiently. Spot drills can also be used for plastics and wood products. Tight areas are benefited by the use of a spot drill. This bit can effectively make a hole without splitting or breaking the material.The spot drill will also increase the accuracy of the secondary drill, or the drill that is to be used afterward on the same hole.

Not all drills are the same. Two popular drill types, a spotting drill bit and a center drill bit, may not appear much different from each other, but the two have very distinct purposes. Though it is possible to use a center drill where a spotting, or spot, drill could be used, and vice versa, it is not recommended.

The center drill is made of a high carbide material and is used for metal working. A center drill is used for making a starter hole in cast iron, aluminum, copper, steels, and many other alloys. The center drill is good for metals because the drill does not easily move off target when pressed against the metal. It is shorter and sturdier than some other bits that may bend under pressure or slide away from the point to be drilled. A dull drill bit will not cut as nicely and can also make holes that are not accurate. It is important to use a sharp center drill when performing these tasks.

WhizCut has been looking for a long time to improve the industry standard lay down thread turning inserts with three cutting edges. As specialists of small part machining we have developed a stand up insert. This enables us to design a threading insert with four cutting edges with increased performance. We have developed the threading inserts in geometries mostly common in Swiss type automatic lathes and use a carbide grade which has shown great performance in these sizes.

The WhizThread inserts and toolholders are designed to give the insert the most stable position. The resulting clamping force is diagonally through the insert and toolholder. This forces the insert back into the toolholder’s pocket and maximizes support. This unique system with its solid clamping will produce a better product and have longer tool life than any other tooling setup. The tool holders are very suitable for Swiss Type Automatic Lathes. Tool holders for threading inserts are available from 8 mm to 1 inch square shafts.

Toolholders are also available in a WhizHip version with high pressure coolant through. With WhizHip it is possible to run high pressure coolant through the tool holder. The coolant is automatically aimed at the insert at a perfect angle for optimal cooling of the insert cutting edge and greater control of the developing chips. The WhizHip toolholders use a 1/8” NPT connection to connect the coolant from the machine. There is therefore no need to invest in any special gang plate.

A center drill is a shorter, thicker drill with a tapered, or cone shaped end that is much thinner than the shaft of the drill. This end of the drill is used to create a starting point for another drill. The center drill can also drill an indentation so that a screw will lay flush with the surface. A center drill also does not catch or grab the surface being drilled. A center drill is also referred to as a combined drill or a countersink.

All WhizThread thread turning inserts have four sharp, fully ground cutting edges. The threading turning inserts all have a positive cutting rake ensuring the best chip control possible when threading. The combination of a high positive cutting rake and a ground cutting edge makes the WhizThread inserts useful for most types of material and applications. All inserts are developed for maximum stability and performance. The carbide allows the insert to have a very sharp, but still strong edge. This makes the threading inserts suitable for materials which are difficult to machine, such as Titanium and Super Alloys. The combination of the best grades of carbide, the most suitable geometries and sharp cutting edges will ensure you getting the best tooling possible for your threading applications.

The WhizThread tooling system can take use of the world renowned WhizFix tool holder system, which enables the operator to index the insert in the machine without taking out the tool holder.

A spot drill does much the same as a center drill, but there are two differences. One is that the spot drill is thinner and does not have the conical ends that the center drill does. The second difference is it's accuracy. The spot drill tends to be more precise in drilling a starting point. The reason is that the spotting bit does not have grooves, or spirals, that do not go all the way up the bit shaft. This gives the bit more sturdiness and is less likely to wobble.
