When you need reliable metal drilling with SDS Plus compatibility, choose bits designed for longevity and precision. This guide highlights five SDS drill bit sets that perform well on metal surfaces, yet also cover common job-site needs such as wood, masonry, and general drilling efficiency. Ideal buyers include professional contractors, DIY enthusiasts, and homeowners tackling metalwork or mixed-material projects. Below is a quick summary of the top picks and why they matter for metal work.
| Product | Best For | Why It Stands Out |
|---|---|---|
| Metal and Wood | Metal bits use grounded high-speed steel with 135° split point for reduced walking; convenient SDS-Plus shank | |
| Metal, small holes | Shorter shank to prevent hammer mode damage; high-speed steel for longer life | |
| Metal, mixed metals | Cobalt M42 alloy provides high heat resistance and extended life on metal work | |
| Concrete and mixed projects | YG8C carbide tips; versatile set with storage case for on-site use | |
| Concrete and masonry | 4-Cutter cross-tip design for fast drilling in hard materials; universal SDS Plus shank |
Makita B-59243 5 Pc. Assorted SDS-Plus Drill Bit Set
Best for metal work that also requires wood drilling. The set uses Sds-Plus shanks for operator convenience and a 135° split point geometry to minimize walking in metal and wood. The metal drill bits are made from grounded high-speed steel (hss-g) for longer life, making this option a solid choice for mixed-material projects. Caution: Do not use the set with non-SDS chucks if your tool does not support SDS Plus.
Makita B-59106 1/8″ x 3-7/8″ SDS-Plus Drill Bit
Strong choice for precision metal drilling with a compact profile. The shorter shank helps prevent damage from accidental use in hammering-with-rotation mode on rotary hammers. Made of ground high-speed steel (hss-g) for longer life, this bit is best for small-diameter metal holes and tight spaces. Limitation: only the 1/8″ size is listed in this set, so larger metal holes require additional bits.
Bosch CO14B 14-Piece Set
Best for high-heat metal drilling and hardened surfaces like stainless steel and cast iron. The cobalt M42 alloy bits deliver longer life and improved heat resistance, making them a reliable long-term choice for metalworking tasks. This set is suitable for professionals who demand durability in metal drilling. Caution: cobalt bits may be more brittle in very hard materials; use steady, controlled feeds to minimize breakage.
TGFTGF 17-Piece SDS Plus Rotary Hammer Drill Bits
Best for versatile masonry work and mixed-site projects. Features durable YG8C carbide tips and a full set of sizes with a sturdy storage case for portability. Although primarily designed for concrete and masonry, the SDS Plus shank ensures compatibility with most hammer drills. Caution: not intended for non-SDS chuck systems; use with compatible tools only.
Kinspire SDS Plus Masonry Drill Bit Set
Best for durable masonry drilling with a cross-tip design that reduces wander and increases hole quality in concrete and brick. The universal SDS Plus shank provides compatibility with a broad range of rotary hammers. Limitation: focused on masonry; not ideal for high-speed metal drilling compared with dedicated metal-only bits.
Buying Guide: How To Choose SDS Drill Bits For Metal
- Material and alloy: For metal, look for high-speed steel (HSS), cobalt (M42), or carbide-tipped options. Cobalt bits excel in stainless steel and high-heat environments, while HSS bits offer general-purpose durability.
- Shank compatibility: Ensure SDS Plus shanks match your hammer drill. Avoid non-SDS chucks unless adapters are provided by the tool manufacturer.
- Tip geometry: Split-point bits reduce walking on metal surfaces. For masonry, cross-tip carbide designs maximize wear resistance.
- Hole size and length: Choose bits in the required diameter and length for your project. Shorter bits are less prone to bending but may require multiple passes for deep holes.
- Durability vs. cost: Metal-focused bits with cobalt or carbide tips usually last longer in metal work, justifying higher upfront cost for frequent metal drilling.
- Intended age and use-case: For mixed-material jobs, consider sets that include both metal-appropriate bits and masonry or wood bits for versatility.
FAQ
- What makes cobalt bits better for metal drilling?
They resist high temperatures and wear longer on hardened metals like stainless steel and cast iron. - Are SDS Plus bits compatible with all rotary hammers?
They fit most SDS Plus hammer drills, but always confirm shank type with your tool. - Should I use carbide-tipped bits for metal?
Carbide tips are more wear-resistant and suitable for very hard metals but can be more brittle; use steady feeds. - Can I use masonry SDS bits on metal?
Not recommended; masonry bits are designed for concrete and masonry materials, not metal surfaces. - Is a larger diameter always better for metal holes?
Not necessarily; use the correct diameter for the hole required and maintain steady drilling to prevent wanders.
