11/16 Inch Drill Bit For Metal
This drill bit features an 11/16″ diameter with a total length of 6″ and a 3″ working length. It comes in a plastic storage case for organization and transport. The bit uses M35 cobalt with a TiAlN coating, delivering high hardness and oxidation resistance for drilling hard metals like steel and stainless steel. The 135° split point reduces walking on tough materials, aiding accuracy when drilling into stiffer metals encountered around wheel studs.
Speedway Motors 1/2″ Drill Bit For 5/8″ Wheel Studs
This bit has a 1/2″ shank and is designed to drill out hubs and axle flanges for 5/8″ wheel studs. It accommodates a knurl diameter around .685″ and measures 43/64″ (0.6719″) for precise sizing. Built to fit standard drill chucks, it helps streamline stud removal and replacement tasks with reliable performance in metalworking environments.
MACXCOIP Cobalt Drill Bit Set, 13Pcs
The 13-piece MACXCOIP set offers sizes from 1/16″ to 1/4″. The M35 cobalt material and TiAIN-like properties provide robust cutting for hardened metals, including stainless steel and cast iron. A 135° point promotes fast, clean entry with reduced walking, while the set’s storage case helps keep bits organized for quick project setup.
DEWALT Titanium Nitride Coated Drill Bit Set, 21-Piece
The DEWALT 21-piece set features a titanium nitride coating and a pilot point design for longer life and cleaner holes. The shanks are designed to start on contact, reducing the risk of wandering. This set is well-suited for drilling into hard metals around wheel studs, offering a balance of durability and ease of use for professional tasks.
MACXCOIP Cobalt Drill Bit Set, 15Pcs
The 15-piece MACXCOIP set expands your size options from 1/16″ to 3/8″. Featuring M35 cobalt with a 135° point tip and a self-centering design, these bits are optimized to prevent walking when drilling into hard metals. The included index case keeps the bits organized for quick access on the job.
Buying Guide
Key factors to consider when choosing drill bits for wheel stud work include material, point geometry, and coating. Cobalt (M35) bits deliver durability for drilling through hardened metals and stainless steel, reducing bit wear. A 135° split point helps prevent walking, a common issue when starting holes in stiff materials around wheel assemblies.
Coatings like TiAIN or Titanium Nitride reduce oxidation and heat buildup, extending bit life in demanding tasks. For frequent users, sets with a broad size range provide flexibility for drilling studs, hubs, or related hardware without swapping bits. Storage cases help keep sets organized in a shop or on a truck, speeding up project setup.
When selecting among sets, consider your typical material thickness, desired working length, and whether you need a single-purpose bit or a versatile set. For wheel stud work, prioritize bits that maintain accuracy under high torque and provide clean thread ends after drilling or chamfering.
Comparisons to look for:
- Sharpness and edge retention under repetitive drilling.
- Coating durability and resistance to heat and oxidation.
- Shank size compatibility with common drills and impact drivers.
- Size range coverage from small pilot holes to larger studs.
- Storage organization for quick project setup and transport.
