ARNO USA provides a reliable and user-friendly face grooving tool by only needing one spare part. A monoblock holder and a boring bar further expand the range of applications.

Internal grooving tools available with integral or modular blades. Available in inch and metric with shank sizes from 1/2" to 2.00" and KM back ends.

Cobalt drill bits are often the best for drilling into hardened steel. Whereas titanium drill bits only have titanium in the coating, cobalt bits have cobalt throughout. After cobalt drill bits get worn out over time, you can resharpen them.

Titanium drill bits are one option for drilling hardened steel. These drill bits are high-speed steel bits coated with titanium nitride. High-speed steel bits that consist of vanadium and tungsten can drill through soft steel, but they won’t cut through hardened steel.

Carbide is a compound composed of carbon and a metal. Carbide drill bits are tungsten carbide and can contain cobalt for enhanced durability. Carbide drill bits can handle higher temperatures than cobalt drill bits.

The titanium nitride coating has a dark gold appearance, improves wear resistance, and reduces friction. Since the titanium nitride is just a coating, once your drill bit wears down, you cannot resharpen it and maintain its performance level. The titanium layer will no longer be on the drill bit except in the fluting and perhaps on the sides.

Our Business Development Manager, Keith Stroup, does a deep dive into the features and benefits of the entire NC System for you.

Hardened steel is medium- or high-carbon steel that has been given heat treatment, rapidly cooled and tempered. The high amount of carbon in the steel makes it possible to harden the metal.

This versatile tool system can handle axial grooving with efficiency and are specially adapted for face grooving and axial groove-turn work in the bottom of bores.

These drill bits can be tungsten carbide tipped or full body. Carbide-tipped bits can drill through hard, non-metallic materials like masonry. If you want to drill hardened steel with tungsten carbide, use a full-body bit.

NC grooving inserts offer both precision ground and as-pressed geometries capable of side turning in both radial and axial (face) groove operations. Selecting ARNO Grooving tools will ensure success in your demanding materials and applications.

A wide range of internal support blades that accommodate radial grooving applications. Find the base tool holder to best suit your machine requirement in Internal Tool Holders, then select from this array of grooving and groove-turn support blade options.

Cobalt drill bits contain an alloy of five to eight percent cobalt. M35 bits contain approximately five percent cobalt, and M42 bits contain about eight percent cobalt.

ARNO's modular system for radial and face grooving tools offer the ultimate in flexibility. Choose your back-end holder from this array of square shank, VDI, KM, and PSC options, then select the proper blade from the External Blades section.

Face groovingtool range

Once you know which external modular tool holder will fit your machine, select from this wide array of support blades for external grooving, face grooving, and KONTRA face grooving.

Hardened steel is resistant to wear and high-impact pressure, making it a choice material for applications that require hard-wearing materials. These characteristics can also make it challenging to machine hardened steel. Read on to discover the best drill bits for drilling into hardened steel.

If you’re looking for a tool to cut through hardened steel, check out the cobalt drill bit sets at Drill Bit Warehouse. Our premium M42 drill bits come in various lengths to suit your project needs. Shop with us today for high-performance drill bits.

The more cobalt the bit contains, the harder the metal it can drill through. But the tradeoff is that increasing the cobalt increases the drill bit’s brittleness. Be sure to use the appropriate drilling techniques to preserve your cutting tools.
