Best Hex Drill Bits in 2026

Size - Drill Diameter: 12mm / 0.47-inch, Drill Bit Length: 87mm / 3.43-inch, Shank Size: 1/4 Inch(6mm) Hex, Total Length: 150mm / 5.91-inch

Material - The hex drill bit is made of M35 cobalt high speed steel with sharp edge. The surface is coated with titanium, which has higher hardness, better wear resistance and longer service life than ordinary drills.

Feature - 1/4 " hex shank, which can quickly replace the drill bit. The fully ground spiral groove design can quickly remove debris, reduce friction and heat, and drill faster. The 135 ° straight shank split point reduces walking on the working face, making drilling accurate and easy.

Size - Cutting diameter: 8.3mm / 0.327"; accuracy class: H7; cutting flute length: 15mm / 0.59"; shank diameter: 8.3mm / 0.33"; 100mm / 3.94"; cutting direction: right hand

Material - C1/K30 tungsten carbide is a tungsten-cobalt carbide with an average cobalt content of 6%, high hardness, good toughness, wear resistance, high heat resistance, and anti-sticking. Carbide can run at higher speed than high-speed steel.

Features - Straight flute reamers allow chips to collect in the flutes when cutting. Well suited for most applications in shallow cuts. Suitable for use in through holes or holes without interruption, such as keyways.

Size - Cutting edge diameter: 0.6mm / 0.024"; cutting edge length: 10mm / 0.39"; shank diameter: 0.6mm / 0.024"; overall length: 38mm / 1.5"; cutting hardness (max.): HRC45; tool flute type: spiral

Material - The solid carbide drill bit is made of a micro grain tungsten-cobalt alloy with an average cobalt content of 6%, high hardness (HRC92), wear resistance, heat resistance, high bending strength, resistance to stick. it is harder but more brittle.

Feature - Large and spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. With good milling and cutting performance, carbide ensures high working efficiency.

Size - Cutting edge diameter: 1mm / 0.039"; cutting edge length: 12mm / 0.47"; shank diameter: 1mm / 0.039"; overall length: 34mm / 1.34"; cutting point angle: 135 degree; manufacturing technology: fully-ground

Material - M42 steel is a super-hard cobalt high-speed tool steel containing 8% cobalt, with good toughness, high wear resistance, high cutting efficiency, and good hot hardness. Nanoscale gold titanium coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant.

Features - Sharp cutting edge provides fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, saving time and effort in operation. Chamfered shank design for easier clamping and less slippage during use.

Size - Drill Bit Diameter: 6mm / 0.24-inch; Flute Length: 127mm / 5-inch; Shank Diameter: 6mm / 0.24-inch; Total Length: 200mm / 7.87-inch.

Material - It is made of 6542 HSS (high speed steel) steel, which has good toughness and hardness, is not easy to break, and is easy to remove chips. Black oxide surface treatment, good rust resistance long durability.

Feature - The spiral groove design can avoid the displacement of the drill bit during the working process, and at the same time, the debris can be removed more quickly and easily. Sharp cutting edges provide smooth cutting without burrs.

Size - Cutting Diameter: 2mm / 0.08", Flute Length: 60mm / 2.4", Shank Diameter: 2mm / 0.08", Total Length: 100mm / 3.9", 10 x Extra Long Drill Bits

Material - These drill bits are made from high-speed steel for high hardness and durability, sturdy and having long service time.

Feature - The twist design is adopted to center the tool tip and improve the cutting accuracy. Prevents the bit from displacement during work, and removes debris and particles more easily.
