DCM INDEXABLE HEAD DRILLS DCM

Product catalog summary

Overview: The document provides technical specifications and guidelines for DCM Indexable Head Drills, which are designed for drilling operations with a range of diameters from Ø10.0 to Ø20.0 and a drilling depth of 8xD.

Specifications: The drills are available in various designations, each corresponding to specific diameter and depth capabilities. The document lists the designations such as DCM 100-080-16A-8D through DCM 200-160-25A-8D, indicating the drill diameter and depth.

Drilling Heads and Mounting: The document specifies the range of drilling heads and emphasizes not to mount smaller heads than specified. It also provides guidelines for mounting procedures, recommending both through tool and external coolant supply for stationary drill applications.

Machining Data: The document includes machining data for DCM drills, highlighting the first choice grade as IC908. It advises on reducing cutting data by 20% for 8xD ratio usage and provides specific feed rates and cutting speeds for different drill diameters and material conditions.

Material Compatibility: The document categorizes materials into groups such as non-alloy steel, low alloy steel, high alloyed steel, stainless steel, cast iron, aluminum alloys, copper alloys, and non-metallic materials. It provides specific hardness values and recommended cutting speeds for each material type.

Recommendations: The document suggests using internal coolant supply when machining austenitic stainless steel and reducing cutting speed by 10% when using external coolant supply only. It also advises selecting chipformers based on geometry range recommendations.
