Bordo Cobalt Spiral Flute Titanium Aluminium Nitride (TiAlN) coated step drills offer unparalleled performance when drilling hard metals such as stainless steel.
HSS-Co5 material provides increased performance and tool life when machining tough steels.
Bordo step drills are ideal for electrical contractors, sheetmetal workers and auto mechanics.
Step drills are designed for drilling repetitive holes in steel, stainless steel, copper, brass, aluminium, plastic, plexiglas, laminates and many other thin materials.
High performance point for faster starting and reduced bit wander.
No pilot hole required.
Stepless drilling in the thinnest sheets.
Burr-free drilling without sheet deformation.
Automatic deburring.
Spiral flutes enable easier tool penetration.
Titanium Aluminium Nitride (TiAlN) is a thin film coating that was developed from Titanium Nitride.
TiAlN offers higher temperature resistance than TiN, as well as slightly higher hardness and especially higher hot hardness (i.e. the hardness at high temperatures).
It is primarily used in high temperature environments above the limits of TiN usage.
This coating works by forming a thin surface layer of Alumina (Al2O3), or Aluminium Oxide ceramic.
Tungsten Carbide Tipped Hex Shank Ceramic Tile Drill Set
These Rotary Only ceramic tile drills provide outstanding performance and extended tool life in hard ceramic materials.
They feature a unique cutting edge geometry in conjunction with high temperature brazing to ensure reliable and accurate drilling in multiple hole applications.
Use of water cooling will extend bit life.
Although these drill bits are not recommended for drilling vitrified porcelain, their superior multi-facet tungsten carbide tip enables them to drill most materials of this type, albeit with a reduced tool life.
Specifically engineered for use in impact drivers these bits are also fully compatible with conventional rotary drills.
1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
The Bordo range of Self Feeding Wood Bits are ideal for drilling large diameter holes in soft woods for plumbing and conduit penetrations and a wide variety of other applications.
7/16″ hex shanks to suit drills with 1/2″ (or larger) chuck.
Precision milled shank which eliminates wobble and runout.
Spurs on the outside diameter cut holes cleanly and accurately.
Dual inside cutting planes shave hole radius for clean, smooth holes without pressure.
Fored in one piece from high carbon steel for maximum strength under the toughest drilling conditions.
