Find the Right Cobalt Drill for Abrasive Metal
Regal Cutting Tools offers a full line of cobalt drills for metals such as cast iron, titanium, stainless steel, and hard alloys.
Combining superior heat resistance with the ability to withstand extreme heat, cobalt drill bits from Regal present the best option for boring into hard materials. The cobalt content is distributed consistently through the bits’ alloy construction. They can be sharpened with no reduction in hardness or wear resistance, so they last longer than other bits. This makes them in the long run an economical alternative to titanium-coated bits, which also are designed for hard workpieces, but whose coatings get sheared off when they are sharpened.
Use this guide to select the right Regal cobalt drills for your application:
• Cobalt Heavy Duty 135° Split Point Bronze Jobber Length Drills
Jobber length drills provide all the reach needed for most common drilling jobs, while maintaining the rigidity required for drilling hard materials at high speeds. The 135-degree split point on these bits facilitates hole-starting by requiring less force than a 118-degree point in order to bite into the material. Once the hole is started, the wider angle point also keeps the bit in place and prevents its “walking” along the workpiece for a more precise hole. Regal’s exacting engineering gives these cobalt drills for metals and hard alloys the most advanced flute geometry to ensure efficient, consistent chip ejection, adding to tool life and hole quality.
• Type J Cobalt Jobber Length Aircraft Drills
You can identify these drills by their bronze oxide coating for increased wear resistance. Built with the same ease-of-use features and life-extending engineering, these drills are created especially for the metals, innovative designs, and surface shapes found in the aerospace industry. Equally effective and resilient in power feed and portable applications, these cobalt drills for metals such as titanium, stacked aluminum, and other tough applications retain high rigidity and hardness even in red-hot conditions.
• Type F Cobalt Screw Machine Length Aircraft Drills
Constructed specifically for work on aircraft fuselages and wing assemblies, Regal’s screw machine-length cobalt bits for thin metal walls and sheathing have the same features as Type J drills. As an added benefit, their shorter length lends greater precision when drilling tough titanium alloys and composites.
When you need products that can stand up to the friction and heat generated when drilling hard materials at high speeds, consider Regal’s jobber- and screw machine-length drills for metals such as titanium, cast iron, and stainless steel. Cobalt drills may be a bit more expensive, but they are good investments in the long run. The cobalt alloy runs completely through the bit – it’s not merely a coating. So these bits can be sharpened without losing cobalt’s hardness and heat-resistance properties, giving them extended life.
