Best Hex Drill Bits in 2026

【20PCS 1/4" Cobalt Drill Bits】20PCS - 1/4"(Drilling Diameter) x2-3/4"(Flute Length)x4"(Overall Length) Metal Drill Bits. This drill bit fits the majority of power drill currently on the market.

【M35 Cobalt High Speed Steel】Industry grade M35 high speed steel drill bit set, harder than 4241 HSS used in other similar drill bits set. These drill bits also contain 5% Cobalt, which increases wear-resistance and durability.

【Fully Ground Process & 135° Split Point】Fully ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance. 135° split point with straight shank prevents walking and makes drilling precise and faster. No center punch is needed.

【20PCS 3/16" Cobalt Drill Bits】20PCS - 3/16"(Drilling Diameter) x2-5/16"(Flute Length)x3-1/2"(Overall Length) Metal Drill Bits. This drill bit fits the majority of power drill currently on the market.

Carbide Tipped: Carbide-Tipped bit heads more stable, harder, more durable, extra-long tool life. The SDS PLUS drill bit will drill holes in concrete faster and easier.

Special Flute Design: The wider and deeper U-shaped flute design cleans debris out fast for easier, efficient drilling, work time longer.

SDS Plus Shank: The shank has two types of grooves (TOTAL OF FOUR). The smaller grooves fix bit in the chuck. The larger grooves allow bits slipping in the chuck when working, enhancing the drilling torque and hammering energy.

Black gold high speed steel is the long lasting material when it comes to common drill bit materials, not only will the bit's structural integrity withstand tremendous heat and wear, but more importantly black gold bits can drill through tougher materials than common HSS bits.

With a 135 degree split-point, these drill bits will catch on the work-surface with greater ease and not wander all over the surface making scratch-marks. This means that after securing the bit in the machine all that is needed is a steady hand to point and apply pressure, and that's it.

The straight round shank of our bits means you can use this drill bit with nearly all types of machines.

M35 HSSCO High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.

Black and gold polished treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge.

135-Degree split point for accurate centering and fast penetration and round shanks allow use with a wide variety of toolholding systems.
