BORDO Red Band HSS-Co TiAlN Tough Treatable Steel Drilling

Bordo Metric Red Band HSS-Co TiAlN Coated Twist Drills for Tough Treatable Steel.
DIN338
130Â° UX point with two helical parabolic flutes with 33 degrees of helix angle.
The mechanical properties of materials are influenced diversely by the addition of alloying elements and heat treatment processes, resulting in some high-strength, quenched and tempered steels or hardened steels.
This range has its own unique set of machining requirements which are satisfied by the Red Band – Tough Treatable Steel – Series.
TiAlN coating increases tool surface hardness to 87Rc.
For machining materials with Hardness < 470 HB : Tensile Strength <1500 N/mm2.

BORDO White Band HSS-Co TiAlN Cast Iron Drilling

Bordo Metric White Band HSS-Co TiAlN Coated Twist Drills for Cast Iron.
DIN338
118° / 70° DX point with two helical flutes with 33 degrees of helix angle.
A highly abrasive material with damping and thermal conductivity, high strength and resistance to wear. Cast Iron is used extensively for mass produced components.
The White Band Series is designed for this specific purpose. TiAlN coating increases tool surface hardness to 87Rc.
For machining materials with Hardness < 300 HB : Tensile Strength <10900 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.
