Can be re-sharpened using a high quality grinding wheel.
Special Offer
7 piece Metric Drill set The ARTU German Drill bits are suitable for all materials. Concrete, masonry hardened steel, glass, ceramic, wood and many other surfaces can be drilled easily.
Special negative grinding on the tip means, no drifting during initial drilling. No centre punch needed - eliminates "walking.
Robust titanium and tungsten carbide tip, chrome vanadium shank and precise, high tech soldering (which handles up to 1100?C) makes up this multi purpose drill bit. You will never have the tip fall out like masonry bits. You can now drill brick into steel, wood into brick and concrete in bar steel without damaging the tip.
These new profile line drill bits ensures increased performance and cutting speed, as well as a longer life.
One drill bit will do all your work whether you are a DIY or fully fledged trades person or farmer.

Drilling InstructionsMATERIALS
YOU SHOULD DRILL AS FOLLOWS
All Kinds of steel
Drill at 2000 RPM minimum speed on a hard support. (No Wood). Preferably in an upright drilling press/machine.
The support should be of the same material as that being drilled otherwise use a flat iron.
Iron can be drilled with hand drill at 2000 RPM. Most effective on hardened steel. Not for continuous use on mild steel.
Use lubrication on all types of steel
Granite, Stone, Concrete
Drill at approx 1000 RPM with or without percussion. If you hit reinforcement concrete continue drilling without percussion at 2000 RPM.
Granite drill slowly at no more than 300 RPM.
Ceramic Tiles & Marble
Drill at approx 500 RPM.
No need to punch or score to centre hole
Centre drill by applying moderate pressure and turning drill.
Must use sharp drill bit. Use - with or without percussion
Marble at approx 300 RPM using water as a coolant.
Porcelain & Ceramic
Drill very slowly, best to use hand drill or alternatively use an electronic/ battery operated drill no faster than 500 RPM. Must use sharp drill bit. Use liquid coolant
Glass & Crystal
These surfaces require slow speed and light pressure. Manual hand drill recommended or slow speed on variable speed drill.
Centre the drilling spot by turning the drill to and fro using turpentine as a lubricant.
For plate, glass or mirror use a flat support and drill from both sides. Bottles should be fixed to a lathe and drill as above.
Wood & Plastics
Drill approx 100 RPM on a wooden support.
Stainless Steel
Drill slow at approx 1000 RPM and use a cutting fluid.
