Our 1st recommended grade for turning steel. Surface smoothing technology significantly suppresses adhesion of work material components. Achieves long, stable tool life with various cutting speeds and work materials

The tip angle of a masonry bit is often greater than that of a metal bit. A masonry bit has a different tip angle than an HSS bit, which is 135°, giving it extra strength. It uses both rotational and hammering forces to punch a hole as it drills.

HSS bits are tough and resistant to heat. As a result, HSS is suitable for high-speed operation and provides a long-lasting performance.

High-speed, high-efficiency grade with great high-temperature strength, which realises excellent wear resistance in high-efficiency machining

General-purpose grade with excellent wear resistance, fracture resistance, and thermal shock resistance, suitable for machining of cast iron and exotic alloys

High-speed, high-efficiency grade with great high-temperature strength, which realises excellent wear resistance in high-efficiency machining

HSS drill bits are suitable for drilling iron, steel, and other metals such as brass, copper, and aluminum alloy. When drilling metals, HSS drill bits are more resistant to the heat created by the high-speed operation. Their resilience is so impressive that it can reach up to 650°C when operating.  As a result, they can be employed at high drilling speeds on hard surfaces.

Masonry bits are usually used with a hammer drill.  It is made of carbon steel and has a sloping tip frequently coated in carbide to give it more strength. Their large arrow-shaped heads help you identify masonry drill bits. The cutting tip of a conventional masonry bit is ground at an angle with no spur point in the center.

Tensile stress removal of the coating layer greatly improves fracture resistance. Achieves long, stable tool life during heavy interrupted cutting

Our 1st recommended grade for turning exotic alloys as it realises stable tool life with high-speed, high-efficiency machining

Superior fracture resistance, providing excellent stability in interrupted unstable cutting and when cutting mill-scaled work

High-hardness cermet with outstanding wear resistance and toughness. Realises high dimensional accuracy for continuous steel machining or finishing of powdered metal or cast iron

An SDS drill bit does not need to be tightened like an HSS drill bit. Instead, simply insert it into the SDS hammer drill's designated slots, and it will remain in place. Drilling the hole using an SDS drill bit ensures that you will go all the way through hard surfaces such as concrete faster and more efficiently.

SDS or "Spannen Durch System" drill bit was designed initially by Bosch features guiding slots. The shank is still circular, but at the very end, it becomes square and contains slots to be inserted into a hammer drill.

Combines a high-hardness carbide substrate with excellent wear resistance and a new CVD coating with improved coating strength to achieve both excellent wear resistance and fracture resistance. Achieves long, stable tool life during high-speed cutting

Development of crater damage is suppressed by controlling the orientation of the alumina crystal grains. Achieves long, stable tool life during high-speed and high feed cutting

100% diamond that directly binds nano-order diamond particles with high strength. Demonstrates optimum wear and fracture resistance as well as the best edge sharpness

Tough grade for titanium machining with excellent fracture and thermal resistance. Perfect for interrupted cutting and mill-scaled work

CarbideTurninginserts

A HSS drill has a circular shank inserted into the drill and is kept in place by three jaws that tighten around the shank. The problem with this configuration is that the jaws may not grip the shank tightly enough, mainly when the drill is in operation.

One significant distinction between a HSS drill bit and an SDS drill bit is how the drill bit is chucked or fastened inside the drill. HSS drill bits are compatible with any standard chuck.

Employs Brilliant Coat PVD coating with excellent lubricity to provide better wear resistance and consistent surface finishes in low-speed cutting applications such as machining of small products or low carbon steel

Alumina coating with even higher strength balances outstanding stability and wear resistance in mill-scale work on forged material. Gold-colored coating makes used corners easily identifiable

The primary distinction between masonry and an HSS drill bit is their function. HSS drill bits are typically used for metals, whereas masonry drill bits are used for concrete bricks and other comparable materials.

It's pretty forgiving when it comes to hand drill and drill press operations. HSS is also very economical since it can be reused and resharpened to extend its life. In addition, HSS drill bits are sometimes coated with black oxide or titanium to prevent corrosion and reduce friction.

High-hardness cermet with outstanding wear resistance and toughness. Realises high dimensional accuracy for continuous steel machining or finishing of powdered metal or cast iron

The shanks of SDS and SDS-Plus drill bits are interchangeable and have a diameter of 10 mm. Unfortunately, the spline is not compatible with SDS-MAX drill bits. However, you can find after-market adapters so that you can use these drill bits interchangeably.
