The drill press vise is an essential tool for drilling on a drill press. The vise is clamped to the work table. It holds the work piece and allows the drilling of right size of the hole in the perfect location to the required depth. The work piece will not move and damage the hand or break the drill bit.
There are different brands, types and sizes of the drill press vises available in the market. You need to understand many things before you can tell what the best drill press vise is for you. The best drill press vise will depend upon the purpose for what it is used, the accuracy required, ease of operation and the life of the vise.
Some most commonly used types of drill press vises are described below. The vises are used in different industries. There are other special purpose vises also available
1.The Standard Vise
It Is the simplest of all. This vise is equipped with two precision ground parallel jaws that clamp the work piece and hold it secure. The vise is generally clamped to the drilling machine table with bolts. One jaw is fixed, while the other can be moved forward or backward with the help of a threaded lead screw to hold the work. It is best for general purpose use where the jobs are not frequently repeated.
2. Circular Round Base Vise
The circular base provides for easy rotation for drilling different holes. It is Ideal for many drilling machines and jobs. These vises have radial slots. There is usually one horizontal and one vertical V to hold a round work piece. It is provided with an adjustable base, which can swivel over complete 360A in a horizontal plane.
3. The Tilting Drill Vise
It is very similar to a table vise, except that it can also be tilted to 90A to become perpendicular to the work table. A robust quality tilting vise is best suited for using when drilling at an angle. It is provided with a angular scale to set the angle.
4. Self Centering Vice
In this type of vise, the moving jaw itself centers the work piece. It is an ideal choice for a fixed table type machine. Once you set and locate the work piece, the next piece will be centered automatically.
5. Cross Slide X- Y Axis Vise
It is two axis vice. In some designs the moving jaw runs over a stabilizer bar that prevents the deflection of jaws. It is not a very high precision vise, but it is ideal for light jobs.
General Quality Requirements
It should have a robust solid construction or have strong ribs for heavier jobs and manufactured from high tensile grade cast iron or SG cast iron and machined to the standard or required accuracy. It should be finished with enamel paint for rust prevention and wear resistance and better finish. The base and sides should be precision machined/ground to offer stability and accuracy of operation.
Long mounting slots are preferable for easy adjustment and fixing on the machine work table
Screw or Spindle
The spindle should be made from carbon or alloy steel and precision machined to move in the gun metal nut without play so that the jaw does not lift up or move aside.
It should be made of gun metal and precision machined to form the square threads matching the screw with minimum play.
Both jaws with vertical and horizontal V slots are more useful for general purpose use. Some jaws have rebates on their top. The best jaws are made of hardened steel and accurately ground.
