Delta Point drills have a multi-faceted cutting tip.
Rather than try and modify existing point types, or tweak the grind angles, Delta Point tip design required a revolutionary re-think of drill tip function.
The overall length of the cutting edge significantly exceeds that of conventional drills.
This means more edge doing the cutting and the results are simply extraordinary.
Drilling times for a range of split point and Delta Point drills consistently showed that Delta Point bits were twice as fast in mild steel.
During independent lifetime testing Delta point drill bits averaged 609 holes in 20mm mild steel, ten times more holes than split point drills.
DRILLS FASTER LASTS LONGER.
Bright Finish Twist Drills have no surface treatment and are supplied in the as-ground condition. These tools are suitable for general purpose use, particularly for non-ferrous applications.
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.

One piece solid core design is significantly more durable than the conventional two piece design that utilises a hex sleeve on a standard round drill bit.
Specifically engineered for use in impact drivers these bits are also fully compatible with conventional rotary drills.
135° split point delivers a precision start and prevents bit wander for fast, accurate holes.
Premium quality M2 HSS ensures extreme performance and long bit life.
1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
