Regal’s Carbide Drills Are a Cut Above the Rest: Sharp, Precise, Long-Lasting
When it comes to speed and precision, carbide twist drills are still king in many metal-drilling applications. Their ability to retain their sharpness keeps production humming along and holes perfectly finished, even at the hottest temperatures. Of course, they cost more than shorter-lived high-speed steel drills, but Regal Cutting Tools’ line of solid carbide and carbide-tipped bits bring the hardness you need to drill hardened steels, cast iron, and tough non-ferrous alloys.
As a leading carbide drill manufacturer, Regal offers three primary drill categories that deliver carbide’s benefits to various tasks.
Carbide-Tipped Jobber-Length Drills
Since carbide is significantly more expensive than high-speed steel, brazing carbide tips onto HSS shafts can save money compared to solid carbide tools while still offering many of carbide’s superior characteristics.
Best used for bronze, copper, and aluminum in addition to cast iron – though not recommended for steel, carbide-tipped twist drills give users the best of both worlds:
- Cost and overall performance in the midrange between solid carbide and HSS
- Carbide’s long-lasting hard cutting edge and high temperature drilling
- Carbide’s accuracy and precision
- Carbide’s long run times thanks to superior wear resistance
- High-speed steel’s shock-absorption
- HSS’s fracture resistance
Regal’s carbide-tipped drills come in sizes ranging from 1/8-inch to ½-inch in 64th-inch increments.
Royal HP AlTiN-Coated Solid Carbide Drills
Long, assembly line-type production runs may require the micro-grain carbide engineering Regal employs in the manufacture of its AlTiN-coated solid carbide twist drills. The coating and production process combine to enable these bits to stand up to the high heat and abrasive stress created by cast iron and some plastics.
Long runs often require high speeds that increase productivity without sacrificing quality, and these drills are up to the challenge, thanks to the layer of aluminum oxide the coating produces to reduce heat and friction without the need for coolant.
Best for producing sharp, smooth, clean holes up to three diameters deep, these carbide twist drills are fitted with 140-degree start points for easy self-centering starts and wide flutes to facilitate chip removal.
Royal HP AlTiN-Coated, Coolant-Through Solid Carbide Drills
In applications where coolant can be introduced through the spindle, Regal’s AlTiN-coated, coolant-through carbide twist drills are the obvious choice for the most extreme speed and heat conditions required in high-production scenarios. By spraying coolant through the tool and onto the workpiece, these drills keep the temperature at the cutting point manageable, aiding in chip ejection, and adding lubricity.
The results include:
- Longer tool life by managing friction, abrasion, and heat
- Maximum production by allowing higher feeds and speeds
- Lower cost per hole by reducing the need for boring, butting, and other finishing steps
Regal’s AlTiN-coated, coolant-through solid carbide twist drills product line includes bits in various lengths capable of drilling up to 10 times diameter.
