High-speed steel spotting drills are the most common choice for a wide range of drilling applications. High-speed steel drills are typically less brittle than cobalt or carbide tools. Also known as hole-starting drill bits or spot drills, these short drills make starter holes that help stop drill bits from walking (or moving) as the hole is drilled deeper with a drill bit.

The SDS-Max shank on these drill bits prevents the bits from slipping in high-torque drilling applications when creating large, deep holes in brick, block, and concrete. The bits install into compatible rotary hammer drills with SDS-Max chucks, and they can be changed in the chucks with one hand. SDS-Max chucks have spring-loaded balls that fit into the grooves on the bits' shanks to hold the bits in place in the chucks.

Solid carbide spotting drills are harder than cobalt steel and high-speed steel spotting drills and provide good wear resistance when drilling into the toughest materials. Sometimes called hole-starting drill bits or spot drills, these short drills make starter holes that help prevent drill bits from walking (or moving) when the hole is made deeper with a drill bit.

Cobalt steel spotting drills provide more wear resistance at higher speeds than high-speed steel spotting drills and are suitable for drilling into hard materials. These short drills (also known as hole-starting drill bits or spot drills) create starter holes that help keep drill bits from walking (or moving) when the hole is drilled deeper with a drill bit.

For simultaneous processing of hole chamfering and centering.

The bright finish on these straight-flute drill bits is unaffected when the bits' cutting edges are resharpened. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They require a rigid setup such as a drill press.

Hybrid spur and ship auger drill bits have a solid center and offer more rigidity in aggressive drilling tasks than auger drills with a hollow core. They can drill into nail-embedded wood, and they have open spiral flutes that provide efficient chip removal. Each bit has a self-feeding tip that pulls the bit into the workpiece and helps prevent it from moving, or walking, during drilling.

Economizers integrate into HVAC systems and help to improve the system efficiency by changing the system's supply air between outdoor air and the HVAC return. This allows the HVAC system to use outdoor air to condition the space rather than actively heating or cooling, reducing costs and system runtime.

It is also ideal for centering, chamfering, deburring at hole entrance. TiN coating has made it possible to achieve higher speed and longer life. Centering processing, chamfering processing, deburring of hole entrance.
