Featuring an innovative geometric blade design, these bits ensure faster cutting speeds and reduced chip jams, making them suitable for a wide range of industrial applications. The set includes a comprehensive range of cutting diameters from 7/16 inch to 1-1/16 inch, with a consistent cutting depth of 25.4mm. Crafted from M2AL high-speed steel, these drill bits offer superior wear resistance and hardness, rated at HRC62.5-67.5. The Weldon shank design ensures compatibility with most major magnetic drill brands. The kit comes complete with a portable carrying case, a hex wrench, and two pilot pins (4.74mm x 77mm and 6.35mm x 77mm) to facilitate precise positioning and efficient chip ejection. Whether for professional shop work or heavy-duty drilling, this kit provides the tools needed for smooth and reliable operations.

The VEVOR 13-piece annular cutter set is designed for metal fabrication professionals and heavy-duty shop environments requiring high-precision hole drilling. These M2AL high-speed steel bits deliver exceptional durability and rapid cutting speeds, making them ideal for drilling through tough structural steel. While they offer superior performance, the 25.4mm cutting depth limit means this set is best suited for plate work rather than extremely thick beams or deep-bore applications.

Extended Product Information
FAQs
What is the maximum cutting depth of these bits?
These bits have a consistent cutting depth of 25.4mm.
Can these be used with a standard handheld drill?
No, these are annular cutters designed specifically for magnetic drill presses with compatible Weldon chuck systems.
What does the HRC rating mean?
The HRC rating refers to the Rockwell C Scale, indicating the hardness of the steel; at 62.5-67.5, these bits are highly resistant to abrasion.
Are the pilot pins replaceable?
Yes, the kit includes two standard size pilot pins, and standard replacements can be used if they become damaged.
What should I use for lubrication?
A high-quality sulfur-based or synthetic cutting oil specifically designed for metal drilling is recommended to maximize tool life.
Troubleshooting
Bit is wandering during initial cut
Ensure the pilot pin is fully seated and the magnetic base is firmly locked to a clean, flat steel surface.
Excessive heat and smoking during drilling
Increase the flow of cutting lubricant and verify that the feed pressure is consistent; do not let the bit 'ride' on the surface.
Slug is not ejecting properly
Clean the pilot pin channel within the cutter to remove compacted chips that may be preventing the pilot pin from pushing the slug out.
Pros and Cons
Pros
High hardness rating (HRC62.5-67.5) ensures long service life
Universal Weldon shank fits most major mag drill brands
Includes essential accessories like pilot pins and a hex wrench
Innovative blade design minimizes heat and chip jams
Cons
Limited to a 25.4mm cutting depth
M2AL steel requires consistent lubrication for optimal performance
Carrying case takes up significant workspace in smaller shops
Setup, Compatibility & Care
Setup: Insert the appropriate pilot pin into the cutter before mounting the bit into your mag drill chuck. Ensure the Weldon shank flats are aligned with the set screws on your drill's chuck.
Compatibility: The universal Weldon shank is designed for compatibility with most standard magnetic drilling machines. Always verify your machine's chuck size before installation.
Care: After each use, wipe the cutters clean of metal shavings and cutting oil. Inspect the teeth for signs of chipping or dullness. Store the bits in their designated slots within the carrying case to prevent edge contact, which can cause premature dulling. Keep the bits lightly oiled to prevent rust if storing in humid environments.
