Makita B-65399 Titanium Hex Drill Bit Set
The Makita B-65399 14-piece set uses a titanium nitride (TiN) coating, which provides longer life in demanding tasks. It is designed for 1/4 inch hex impact drivers, offering a 135-degree split point that starts quickly and stays on target, reducing walking. This set is best for professionals who frequently switch between metal and wood work with impact tools. Caution: TiN-coated bits can be more brittle if forced or used in misaligned holes; maintain steady pressure and proper alignment.
DEWALT 12 Pc Black and Gold Drill Bit Set
DEWALT’s black-and-gold 12-piece set emphasizes rust resistance and durability for metal, plastic, and wood projects. The 135° split-point design improves start accuracy and reduces walking in larger sizes, while the tapered core enhances resistance to breakage. This set suits DIYers who want a dependable, all-purpose option with long-lasting tips. Limitation: Some users may prefer higher-end coatings for heavy-duty metal drilling over time.
8 Pack HSS Step Drill Bits (Hex Shank)
These HSS step drill bits come in eight common diameters from 3mm to 10mm. The titanium coating roughly doubles the life of standard bits, and the 135° split point with fully ground flutes helps chips clear and minimizes heat buildup. They are best for light-to-medium metal drilling and plastic work. Caution: Step bits can wear unevenly if used beyond their designed material thickness or on very hard metals.
EZARC M35 Cobalt Stubby Drill Bit Set
The EZARC set uses M35 cobalt steel with a black AlTiN coating for enhanced hardness and heat resistance, ideal for stainless steel and other hard metals. The self-centering tip reduces walking, and the stubby hex shank improves access in tight spaces. Best for: professionals who drill in confined areas or with hard metals. Limitation: Stubby bits have shorter reach, which can limit depth in deeper holes.
COMOWARE Titanium Twist Drill Bit Set 16 Pcs
COMOWARE’s 16-piece titanium-coated twist drill bit set offers classic HSS construction with a durable coating for improved wear resistance. The 1/4 inch hex shank enables quick changes and secure locking in compatible drills and impact drivers. This set is a solid all-purpose choice for hobbyists and professionals seeking a balance of sharpness and longevity. Caution: The dry-coating surface may wear with heavy grinding; avoid overheating during extended drilling sessions.
Buying Guide: Hex Shank Drill Bits
Why choose hex shank?
Hex shank bits fit fast-change chucks securely, reduce cam-out, and are easy to swap in busy workspaces. They work well with impact drivers and drills, especially for metal and hard materials where quick changes save time.
What materials do you drill?
- Metal: Look for cobalt or titanium coatings, and consider smaller bit sizes for stainless steel to avoid excessive heat.
- Wood: Standard HSS or TiN-coated bits perform well; for large countersinks, step bits may help.
- Plastic: Use sharp tips and slower speeds to prevent melting; ensure bits are properly sharpened.
Coatings vs. uncoated
Coatings like TiN or AlTiN extend life by reducing wear and heat. For frequent metal drilling, coated bits are typically worth the extra cost. For occasional wood or plastic work, uncoated but sharp bits may suffice.
Tip selection
- 135° split point: Reduces walking and starts cleanly in metal and wood.
- Self-centering tips: Helpful for staying on target in metal drilling.
- Stubby bits: Useful in tight spaces but shorter reach; plan your access needs.
Durability and maintenance
Inspect bits for chipping or dulling; avoid applying excessive force or overheating. Regularly clean and store bits to prevent corrosion, especially in humid environments.
Choosing the best set for you
- Best for impact drivers and hard metals: Titanium-coated or cobalt-infused bits with hex shanks.
- Best all-purpose starter kit: A balanced set with a mix of sizes in a hex-shank twist design.
- Best for tight spaces: Stubby hex-shank bits with self-centering tips.
Frequently Asked Questions
- What is the advantage of a hex shank over a round shank? Answer: Hex shanks reduce slipping, improve transfer of torque, and fit faster-change chucks securely.
- Are cobalt bits worth it for metal drilling? Answer: Yes for hard metals; they resist heat and wear better than standard HSS in demanding tasks.
- Can I use these bits with non-impact drills? Answer: Yes, but impact drivers provide the best control and torque for tough materials.
- How do I extend bit life? Answer: Use proper lubricant when drilling metal, avoid binding, and choose appropriate speeds for each material.
- What sizes should I start with in a first hex-shank set? Answer: A core range from 1/16″ to 1/2″ covers most DIY and professional needs.
- Do stubby bits drill deeper than standard bits? Answer: Stubby bits have shorter reach; they aren’t designed for long through-holes but excel in tight spaces.
