BORDO Yellow Band HSS Aluminium Drilling

Bordo Metric Yellow Band HSS Twist Drills for Aluminium and its alloys.
DIN338
130° web thinned point with two helical flutes with 35 degrees of helix angle.
The alloying elements which achieve varying Aluminium Alloys have an effect on the machining properties of these materials.
This generally creates a difficult long chip formation and material which has tendencies to stick to the tool, placing a unique set of demands on tooling. Yellow Band Series contends with these difficulties.
For machining materials with Hardness < 200 HB : Tensile Strength <700 N/mm2.

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.

Reduced shank HSS twist drill.
118° notched point with 30° helix.
Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander.
118° point angles are ideal for use in materials such as mild steel and cast iron.
The 118° point creates easily controlled chips which are wide and thin.
Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating.
This surface aids chip flow and heat dissipation.
The drill is then ground a second time to achieve a bright finish on the shank and cutting edges.
