Do You Know Which Carbide Drill to Buy?

Carbide has long been known to be a material that is strong, durable, and can be used for the cutting and drilling of other materials. Carbide is made from powdered carbide bonded with a metal for extra strength. The combination of metal and carbide makes any tool such as a drill stronger and tougher than the sum of its parts.

But does every drilling and milling tool need to be made of carbide? The clear answer is of course not, machinists can use any kind of tool they want. However, there are very good reasons to use and buy carbide drills and mills for machining.

Why Use Carbide Tools?

Precision tools made of carbide have unique qualities that make them more accurate and efficient than traditional or conventional tools. Carbide gives these tools the ability to cut faster, drill deeper and with more accuracy, and create surface finishing that is finer.

Carbide drills do not dull as easily and that gives these drills a longer lifespan. They also can drill even with short cycle times, which means better utilization for the tool, and reduced risk for tool damage.

Carbide tools are also more cost efficient, as they are more durable than traditional tools. They are made of better quality materials that could endure heat and abrasion for a long time without damaging the work material or the tool.

This means you might spend more on carbide tools now, but they will last longer than conventional drills and mills, and can be used for many different materials. Carbide ceramics are incredibly hard and heat resistant materials that impart these properties on the finished tool, which can make for superior machining when compared to metallic tools.

What Makes a Superior Carbide Drill

So once you’ve decided to buy carbide drills and tools, how would you know which one to buy? Always consider the following when you want to get carbide tools:

Always consider the requirements of a project.

Check the details of your machining project. Carbide drills have bits and shapes that are required for specific applications, so know the demands and requirements of your project so you know which kind of carbide drill to buy.

Choose the right size.

Size matters when it comes to drills, and many standard drills can accommodate 1 mm to 20 mm. But if you are working with an industrial size drill, the scale could be larger. Check the scale of the drilling project and make sure you have the right size for the drill.

Check the drill’s features and length.

You need to check the requirements for the length and design of your project. The depth of the drilling project requires a specific drill length, so make sure you have the right drill length for your workpiece project.

Consider whether the project needs a drill with fluting, as it could demand features that would require flutes. You might also need other tools to meet design specifications, and for these features you might need different bits for your drill.

Best Practices for Carbide Drills

So now you have a carbide drill. Does it also need different ways of handling and storage to protect it from regular wear and tear? Here’s the best practices to handle these tools safely and effectively.

Check the holding system.

Always check the centerline of the shaft when drilling, ensuring that the drill is not shifting from the axis. You need to use a dial indicator to reduce runout.

Get a better grip.

Use a hydraulic grip and avoid using manual fixtures. Using screws and bolts could lessen the quality of the tooling, and could also lower productivity outputs.

Use a coolant.

Using a high quality coolant could also lengthen tool life by 60 percent, because it can reduce friction and pressure during the machining process. Use the right amount and apply it onto your drills.

The Right Drill Needs Proper Utilization

It’s not enough to find the right carbide drill. You need to know the requirements of a project and know how to use it properly. Having these in mind will give you a better understanding of how to use these tools properly, which can save you money and time.
