Top Drill Bit Sets for Metal and Masonry: A Professional Selection Guide
Selecting the right drill bit is essential for achieving clean holes and maintaining tool longevity, whether you are working with hardened steel or dense masonry. Different materials require specific bit compositions and tip geometries to manage heat, friction, and impact forces effectively. For metalworking, high-speed steel and cobalt alloys are standard for their heat resistance, while masonry applications demand carbide-tipped bits capable of enduring the repetitive impact of a rotary hammer. This selection covers a variety of sets designed for different workshop needs, from heavy-duty drilling in stainless steel to structural demolition tasks. Understanding the specific material compatibility of each set ensures you select the appropriate tool for your next project.
When building out a workshop, matching the shank type and coating to your specific power tool is crucial for performance. SDS Plus bits are engineered for the high-impact demands of rotary hammers, whereas hex-shank bits offer quick compatibility with standard impact drivers and drills. Coatings like TiAlN provide additional surface hardness, which is beneficial when cutting through abrasive or hardened materials. While some kits offer versatility through assorted sizes, others are specialized for specific tasks like concrete chipping or drilling thin stainless steel. By reviewing the technical specifications and user ratings of these options, you can better match your equipment to the demands of your specific drilling or demolition requirements.

How to choose
Material Compatibility
When selecting drill bits for metal, prioritize high-speed steel or cobalt compositions. The Crosstar 21Pcs M35 Cobalt Drill Bit Set is engineered specifically for thin hardened steel, stainless steel, and titanium applications. In contrast, masonry-focused sets like the TGFTGF 17-Piece SDS Plus Rotary Hammer Drill Bits and the Bosch HS2161 Moil Point are designed for concrete, brick, and stone. Using masonry bits on metal can result in poor performance and damaged equipment, so verify that the bit material is rated for the specific hardness of your metal workpiece before beginning your project.
Coating and Durability
Surface coatings significantly influence the heat resistance and longevity of drill bits. The Crosstar M35 set features a TiAlN coating, which is beneficial for high-speed metal drilling applications. Titanium coatings, such as those found on the Makita B-65399 Impact Gold set, are often used to reduce friction and improve bit life during repetitive tasks. While carbide tips—like those in the TGFTGF masonry set—offer extreme hardness for stone, they are not a substitute for the specialized cobalt or titanium-coated bits required for effective metal drilling.
Shank Design
The shank configuration must match your power tool’s chuck. SDS Plus bits, seen in the TGFTGF collection, are intended for rotary hammer drills for masonry tasks. Conversely, the Makita B-65399 Impact Gold set utilizes a 1/4 in. hex shank, which is optimized for impact drivers and quick-change chucks common in metalworking. Always ensure the bit shank is compatible with your drill to prevent slippage or mechanical failure. Matching the shank type to your drill model ensures secure seating and efficient torque transfer during demanding metal drilling operations.
Bit Geometry
Geometry dictates how efficiently a bit penetrates material. The Crosstar set includes a bullet point tip designed for self-centering, which prevents the bit from wandering across the metal surface during the initial contact. This feature is critical when working with hard materials like stainless steel or titanium. Other sets, such as the Makita D-59178, offer assorted sizes for versatility, but you must ensure the specific tip design is appropriate for metal rather than general-purpose masonry work, which requires different edge angles for impact-resistant drilling in concrete.
Application-Specific Tooling
It is essential to distinguish between drilling, driving, and demolition tools. The Bosch HS2161 Moil Point is a 20-inch hex hammer steel designed for heavy-duty demolition rather than precision drilling. Never attempt to use demolition steels or masonry-specific SDS Plus bits for metal drilling, as they lack the necessary cutting geometry. For metal projects, rely on dedicated jobber bits like those found in the Crosstar M35 or Makita Impact Gold sets. Selecting the correct tool category ensures safety and protects the integrity of your power tools while achieving clean holes in metal surfaces.
Frequently asked questions
Can I use SDS Plus masonry bits for drilling through metal?
No, SDS Plus bits, such as those in the TGFTGF 17-Piece set, are specifically designed for masonry materials like concrete, brick, and stone. They utilize carbide tips that are not optimized for cutting through metal. Using these bits on metal will likely lead to poor results and potential damage to the bit and your power tool. For metal projects, always choose bits explicitly rated for metal, such as the Crosstar M35 Cobalt set.
What is the benefit of the TiAlN coating on the Crosstar drill bits?
The TiAlN coating on the Crosstar 21Pcs M35 Cobalt Drill Bit Set is designed to provide increased heat resistance and durability during high-speed drilling operations. This coating is particularly advantageous when working with demanding materials like thin hardened steel, stainless steel, and titanium. By reducing friction and heat buildup at the tip, the coating helps extend the functional life of the bits, allowing for more consistent performance when drilling through tough metal surfaces.
Are the Makita B-65399 bits compatible with standard drills?
The Makita B-65399 Impact Gold set features a 1/4 in. hex shank. While these are optimized for use with impact drivers and quick-change chuck systems, they can typically be used in standard drill chucks that accept hex-shank accessories. However, they are not intended for use in SDS Plus rotary hammer chucks. Always verify your specific drill's chuck capacity and compatibility before attempting to secure the bit to ensure a safe and stable connection during operation.
Why should I choose a self-centering tip for metal drilling?
A self-centering tip, such as the bullet point tip found on the Crosstar M35 Cobalt bits, is essential for metal drilling because it prevents the bit from 'walking' or sliding off the target point on smooth or hard metal surfaces. This ensures greater accuracy and cleaner hole placement, which is especially important when working with materials like stainless steel or titanium that can be difficult to mark and penetrate precisely.
Is the Bosch HS2161 suitable for drilling holes in metal?
No, the Bosch HS2161 Moil Point is a heavy-duty hammer steel designed for demolition tasks, such as breaking up concrete or masonry. It does not have a cutting edge capable of drilling holes in metal. Attempting to use a moil point for drilling will not work and is an improper use of the tool. For drilling holes in metal, you should utilize jobber-style drill bits designed for that specific purpose.
Bottom line
For users specifically seeking the best performance when drilling into metal, the Crosstar 21Pcs M35 Cobalt Drill Bit Set is the superior choice. Its composition of M35 cobalt steel and TiAlN coating is engineered to handle the rigorous demands of thin hardened steel, stainless steel, and titanium. The inclusion of a bullet point tip for self-centering makes it highly effective for precision work where preventing bit slippage is paramount. While the Makita B-65399 Impact Gold set is a reliable option for impact-ready applications, the Crosstar set provides the specific material hardness and heat-resistant properties necessary for consistent, high-quality results in various metal-drilling scenarios.
Deciding between these sets requires evaluating your specific power tool and material needs. If you are working with concrete or masonry, the TGFTGF SDS Plus set or the Bosch HS2161 demolition steel are appropriate choices. However, for metal-focused projects, ignore masonry-rated bits and focus exclusively on the Crosstar M35 Cobalt or Makita Impact Gold sets. Choose the Crosstar set if you prioritize cobalt-grade durability for hardened metals. Select the Makita B-65399 if you require a hex-shank bit optimized for impact driver usage. Always confirm your drill's chuck type to ensure the bit shank is compatible before finalizing your purchase.
