High Accuracy Spot Drill for Precise Centering and Drilling Operations
Specially designed for pre-drilling holes in workpieces to provide precise positioning for drilling or tapping for subsequent machining. The compact design of the spot drill and the moderate angle of the drill tip effectively reduces displacement and deviation, ensuring accuracy for subsequent machining.
Description
Main Features
High-precision positioning: A precise small hole can be formed on the surface of the workpiece, ensuring that subsequent drilling or tapping operations will not be offset.
Versatility: Besides being used for positioning, it can also be used for some shallow hole drilling operations.
Multi-material applicability: Suitable for a wide range of materials such as metal, plastic, wood, etc.
High wear resistance: Usually made of high quality cemented carbide or high speed steel for a long service life.
