High Helix Flutes – Jobber Drill Split Point
— Higher helix can also help with chip control by ejecting the chips at a steeper angle.
— High Helix Flutes design allows for increased feed rates up to 2X.
— 135° Split point provides fast penetration and accurate starting
without a center punch.
— Higher helix angles are normally recommended, and perform well on gummy materials
like aluminum, and excel in stainless and heat resistant alloys.
— Recommended for Stainless Steel, Aluminum, Brass and
all other non-ferrous metals.

An essential feature of a twist drill is the helix angle (spiral angle). It determines the process of chip formation. Larger helix angles provide effective removal of soft, long-chipping materials. The high helix brings the stringy chip up and out of the hole for easy disposal.
Smaller helix angles, on the other hand, are used for hard, short-chipping materials.
Twist drills that have a very Small Helix angle (10° – 19°) have a lengthy spiral. In return, twist drills with a Large Helix angle (27° – 45°) have a rammed (short) spiral. Twist drills with a normal Spiral have a Helix angle of (19° – 40°).
