Polished Slot Drill, Diameter: 16 mm

Product Details

A Slot Drill is a type of end mill specifically designed for cutting narrow, straight slots or grooves in a workpiece. Slot drills are similar to regular end mills, but they are specifically optimized for cutting slots with parallel sides, often used in applications like keyways, splines, and grooves. Key Features of Slot Drills: Two Flute Design: Slot drills usually have two flutes (cutting edges), which makes them well-suited for cutting narrow and precise slots. The two-flute design allows for faster chip removal and smoother cuts compared to multi-flute tools. Flat Bottom: Unlike standard end mills, which may have a rounded or ball-shaped tip, slot drills have a flat bottom. This makes them ideal for cutting slots with parallel sides, as they can cut all the way to the bottom of the slot without leaving any rounded or curved features. Straight Cutting Edges: The cutting edges of a slot drill are straight and parallel to the tool's axis, which allows them to create clean, precise slots in materials with minimal lateral deflection. Material: Slot drills are typically made from materials like high-speed steel (HSS), carbide, or coated versions to enhance durability and cutting performance, especially in tougher materials. Shank Size: Slot drills come in various sizes, typically with standard shank sizes like 1/8", 1/4", 1/2", and so on, making them versatile for different applications. Applications of Slot Drills: Cutting Keyways: Slot drills are often used in keyway cutting. A keyway is a narrow, straight slot in a shaft or hub where a key fits to prevent rotational movement between components. Slot drills are ideal for producing clean, precise keyways. Groove Cutting: They are used to create grooves in various workpieces, which could be for functional purposes like fitting parts together or for aesthetic purposes. Spline Cutting: A spline is a series of slots or grooves used to transmit torque between a shaft and a mating part. Slot drills can create spline grooves with precise depth and spacing. Milling Applications: Slot drills are commonly used in milling machines for producing slots or channels in metal or other materials. Their flat-bottom design ensures clean cuts and helps prevent tool deflection. Parting and Profiling: Slot drills can be used for parting operations where a thin strip of material is cut away, as well as profiling tasks where an exact shape or pattern needs to be cut into a material. Engraving: Slot drills can also be used for fine engraving tasks where a straight, narrow groove needs to be cut into the surface of a material.
