BORDO IMPACT Hex Shank HSS Twist Drill Set

1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
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.
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.
Bordo Impact Bits are designed and manufactured for optimum performance in modern impact drivers.
Not only do they offer significantly increased bit life in impact applications but they also offer exceptional performance in standard driving usage.
The impact driver action places high peak torque demands on both insert and power bits.
Our range features a uniquely engineered torsion zone with multi-stage hardening and tempering to dissipate damaging peak loads.

BORDO Blue Band HSS-Co TiAlN Stainless Steel Drilling Metric

Bordo Metric Blue Band HSS-Co TiAlN Coated Twist Drills for Stainless Steel.
DIN338
Multi-faceted point with two helical flutes with 35 degrees of helix angle.
The machining of stainless steels is difficult due to its work hardening properties, toughness and poor thermal conductivity, which places high demands on the cutting tools.
The Blue Band – Stainless Steel – Series has been specifically designed to suit these difficult machining requirements.
TiAlN coating increases tool surface hardness to 87Rc.
For machining materials with Hardness < 350 HB : Tensile Strength <1250 N/mm2.

Reduced shank HSS twist drill set.
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.

Bordo Metric Green Band HSS-Co TiN Coated Twist Drills for Carbon Steel.
DIN338
130° split point with two helical flutes with 33 degrees of helix angle.
The machinability of different carbon steels is as varied as their properties. Soft-tough construction steels place a unique set of demands on the tools.
The Green Band Series of drills and taps have been developed specifically for this range of steels.
For machining materials with Hardness < 250 HB : Tensile Strength <900 N/mm2.
