Manufacturer: BIG DAISHOWA—Americas
Model: Spot and Chamfer

Features

• Implementing spot and chamfer drills can improve the hole location and tool life of a succeeding drill.
• Spot drill bit geometries are short to optimize rigidity and accuracy, with a point angle larger than the succeeding drills to guide them towards the hole’s centerline.
• Parts often have rough, angled, or curved surfaces, leading to poor and inconsistent tool life without using a spot drill bit.
• A spot drill creates a consistent surface, allowing the more delicate and expensive deep hole drill to enter the part smoothly.
• The tool features a four-facet point grind for precise cutting.
• Standard coatings are available to optimize tool life in materials with low machinability, such as hardened steel.
