Core Drills for Automotive Glass Drilling

Product Overview

Core Drill for Drilling Holes in Automotive Glass That Can Also Perform Beveling Simultaneously

This is a core drill designed for drilling holes in automotive glass, which plays a crucial role in improving vehicle safety. It features a chamfering section that performs chamfering simultaneously with drilling, helping to streamline the manufacturing process.

Application

• Drilling Holes in Automotive Glass

Types of Adhesives

• Metal

Product Features

◇ Features grooves that effectively facilitate coolant supply and chip evacuation, maintaining excellent cutting performance
◇ Improves runout accuracy in the seamer section, reducing the load during chamfering
◇ Adopts a design that suppresses chipping on the machined surface

Product Type

One-Piece Type (Standard)
[Features]
・High machining precision achieved through one-piece molding
・Projection length can be adjusted according to machining requirements
・Repairs are possible (Standard type only)

Split Type
[Features]
・The protrusion amount can be flexibly adjusted by changing the seamer position
・Due to its split structure, while machining accuracy is slightly lower than that of the one-piece type, it offers superior adjustability
