Best Inch Hex Shank Drill Bits in 2026

HIGH QUALITY MATERIAL: 5% Cobalt High Speed Steel M35 provide extended tool life compared to ordinary drill bits. Durable and strong

TWIST DESIGN & PERFORMANCE: PRECISE 135°SPLIT POINT, gold oxide finish and round straight shanks. Prevent walking, clear chips and particles faster.Produced by precision fully ground which ensures chips move smoothly.

PROFESSIONAL & WIDELY USE: M35 Cobalt HSS is more suitable for hardened material. Particularly successful in cutting through hard metals such as stainless steel, cast iron, high temperature alloy, titanium alloy, hard plastics and woods, and also can be used for softer materials.

COBALT GOLD OXIDE JOBBER DRILL BITS: 29 PCS high speed steel with 5% cobalt drill bit set resists high heat abrasion while drilling. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures. A gold oxide finish acts as a lubricant and provides wear resistance.

ROUND AND PORTABLE CASE: Say goodbye to constant losing or misplacing your drill bits! Jefe Hex cobalt drill bit set for metal comes with an ergonomic and portable round carrying case with built-in clip. The case can be easily attached to your tool belt keeping your bits within immediate reach!

Proper twist and flute design clears chips and particles fast. Drill bits larger than 3/8" have 3/8” reduced shank for majority drills in the market. Drill bits smaller than 3/8" have three-flat shanks that reduce spinning in chuck.
