Center drill bits, or countersink drills, create small conical depressions or "center holes" in a workpiece. These holes serve as starting points for other machining operations like drilling, turning, or grinding.

A twist drill bit is a common, versatile tool used for drilling holes in materials like metal, wood, and plastic. Its spiral flutes twist around the body, helping to remove material as it rotates.

A drill bit is a tool for creating cylindrical holes in materials like metal, wood, plastic, and concrete. Available in various sizes, materials, and designs, it suits diverse drilling applications.

A ball nose end mill is a milling cutter with a spherical cutting end, used for machining contoured surfaces, curved profiles, and 3D shapes. It's ideal for creating intricate and curved features.

A flat-end mill, or square end mill, is used for machining flat-bottomed slots, grooves, and profiles. It features square cutting edges, unlike ball end mills, which have rounded edges.

A milling cutter is a rotary tool used in milling machines to remove material with multiple cutting edges. It’s essential for shaping, contouring, and creating features on materials like metal, plastic, and wood.

A multi-function tap is a versatile tool combining multiple tasks in one operation, saving time and effort. Its specific features and functions vary based on its design and intended purpose.

A spiral point tap, or gun tap, is a threading tool for metals. Its flutes spiral at a specific angle along the axis, like a spiral flute tap, but it differs in purpose and design, focusing on chip clearance.

A spiral flute tap, or spiral point tap, is a threading tool for materials like metal and plastic. Its flutes spiral up the tap at a shallow angle, distinguishing it from straight flute taps.
