Drill Set-Drill-HSS Drill-Cutting Tool-center Drills

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  (http://maplered.com)  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  (http://maplered.com)  quicker cutting with our products 
3) Marble tile and  (http://maplered.com)  similar: these Material  (http://g654.org) s 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  (http://maplered.com)  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 for drilling plastic, laminate, fiberglass, and  (http://maplered.com)  solid
    surface Material  (http://g654.org) s. But moderate speed is suggested to drill these Material  (http://g654.org) s 
6) Glass: glass should be drilled with a cutting lubricant. An oil-based lubricant
    is better. Water can be used, but not recommended. Make a small reservoir out
    of a piece of string or bit of clay to hold lubricant around drilling area. Drill
    pilot hole if possible, you will get better results for your efforts. Never apply
    excessive pressure to glass. Be sure you are drilling on a flat surface and  (http://maplered.com)  do not let
    the body of the drill slide into and  (http://maplered.com)  hit the glass when the bit exits the hole.
    Glass should be drilled within the speed of 300-600rpm.
