We can supply drills: 1) metal in general metals should be drilled at high speeds not less than 2,000rpm;
A drill press is suggested when drilling metal, and if possible, use a cutting
lubricant, it will help prevent burning during the operation
2) Masonry products: drill at a speed comparable to a typical masonry bit, expect
longer life and quicker cutting with our products
3) Marble tile and similar: these materials should be drilled using a slow or
moderate speed. A hammer action drill should not be used because it will cause
chipping or cracking. A piece of tape placed over the drilling area will help
to prevent chipping and cracking
4) Wood: common holes are easily drilled at moderate speed. However, you might
notice a rougher finish than with conventional wood spades or brad point drill
bits, particularly on soft wood
5) Plastic: the filling action of our products is fantastic for drilling plastics.
Any speed is acceptable
