Question 1

What materials can the RED HELIX 23-piece Cobalt Drill Bit Set drill?

Accepted Answer

The RED HELIX Cobalt Drill Bit Set is designed for drilling hard metals, including stainless steel and cast iron, as well as thick metal, wood, and plastics. Its cobalt construction is suited to demanding drilling applications, while the QUAD EDGE tip and VARIABLE HELIX flute help support efficient cutting and chip removal across compatible materials.

Question 2

How does the QUAD EDGE tip improve drilling performance?

Accepted Answer

The QUAD EDGE tip uses four cutting edges to provide a precise starting point and create smaller chips during drilling. This design helps promote faster material removal while reducing heat buildup. It is also engineered to stay sharper longer, making the drill bits suitable for demanding applications involving hard metals and other compatible materials.

Question 3

What makes these cobalt drill bits more durable for hard metal drilling?

Accepted Answer

The RED HELIX technology combines a QUAD EDGE tip, VARIABLE HELIX flute, and thicker tapered web to improve drilling performance and bit strength. The cobalt construction is rated for up to 15X the life of black oxide drill bits, according to the product information. The thicker tapered web also helps reduce premature breakage during demanding drilling applications.

Question 4

How does the VARIABLE HELIX flute help remove chips?

Accepted Answer

The VARIABLE HELIX flute begins with an aggressive 35-degree helical angle and transitions to 15 degrees toward the end of the flute. This changing geometry is designed to promote rapid chip removal during drilling, helping maintain efficient cutting performance. The design is particularly useful when drilling hard metals and other materials where effective chip evacuation is important.

Question 5

What sizes are included in the 23-piece RED HELIX Cobalt Drill Bit Set?

Accepted Answer

The set includes 23 cobalt drill bits ranging from 1/16 inch to 3/8 inch, with multiple quantities of commonly used sizes. Included diameters are 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64, 1/4, 5/16, and 3/8 inch. The set also includes a customizable accessory case designed for use with PACKOUT organizers.
