At Drill Bit Warehouse, we pride ourselves on being a well-respected drill bit provider that meets ANSI standards and outlasts the competition. We offer cobalt drill bits for hardened steel and abrasive materials, including bronze, titanium, cast iron, stainless steel, and more. To learn more, contact us today about our high-quality drill bits.

Cobalt drill bits can work longer without cutting fluids or cooldown periods, cutting through materials including cast iron, titanium, bronze, and stainless steel. They are also corrosion-resistant but are often fragile and need adequate care.

All items are subject to a 25% restocking fee, this will be deducted from your refund. We also do not refund the original shipping and handling that you paid on the order.

However, carbide drill bits can break apart if misused due to their brittle nature. Moreover, they also make for optimal masonry or stonework.

Carbide drill bits are a high-end option for manufacturing and computer numeric control applications. They are tough, provide high-heat dissipation rates, and maintain an edge for longer than other drill bits.

A perfect finish doesn’t always have to mean spending lots of time and money, and in areas where multiple Bullnose beads meet, these ¾” & 1½"-radius molded corners are the perfect accessories for a faster finish. Bullnose base adapters transition rounded beads to 90-degree corners for installing baseboards.

Some items can not be returned if they are opened. Merchandise that has been worn, used, or altered will not be accepted for return or exchange.

Select items will now be considered final sale including clothing, shoes, wearables, masks, filters, and personal safety equipment.

Choosing between various drill bit types is a difficult task. With so many sizes and shape variations, they all serve different purposes.

Cobalt drill bits often get constructed using steel or another alloy combined with five to eight percent cobalt. Cobalt drill bits make for optimal high-temperature applications and offer extreme durability.

When high-speed steel (HSS) drill bits don’t cut it, choosing between cobalt and carbide drill bits can quickly become time-consuming. Luckily, here are some notable differences that will help save you time during your decision-making and help improve drilling performance.

Due to its rounded surface, a ¾” Large Bullnose Corner Bead provides a unique finish, but can present a challenge during the mudding process. This polypropylene Bullnose Cleaning Tool is designed to allow finishers to easily wipe down compound from this bead (including its splayed version), minimizing your time spent sanding.

Archway Bullnose Corner Bead gives you a rounded, unique finish, but can be a challenge to coat with compound. By using this finishing tool for each coat, you will wipe the bead clean and fill the bead’s notched slots with mud. Suitable for both ¾” Large and 1 ½” Jumbo Bullnose Archway corners.

However, both carbide and cobalt drill bits have minor downsides. Carbide drill bits have a higher price point than cobalt drill bits, along with resharpening difficulties, and will need replacement once blunt. Cobalt drill bits quickly chill on rigid materials, can’t perform high drilling speeds like carbide drill bits, and require resharpening after 100 to 200 holes.

There are many differences between cobalt and carbide drill bits, especially regarding their pros and cons. Firstly, cobalt drill bits can easily resharpen after repeated use, cut through soft or hard materials, and cost less than carbide drill bits. Carbide drill bits last longer than cobalt drill bits, have higher heat resistance, work at very high speeds to decrease manufacturing speeds, and provide toughness to cut through non-ferrous heavy metals and reinforced plastics.
