TUBE AND SHEET DRILLS

Product catalog summary

Overview: This document provides detailed specifications and guidelines for tube and sheet drills made from High-Speed Steel (HSS), Titanium Nitride (TiN) coated HSS, and HSSE-Co 5 with split points. It includes information on sizes, materials, and cutting speeds.

Specifications:

Materials: The drills are made from HSS, HSS with TiN coating, and HSSE-Co 5. These materials are suitable for drilling various materials including steel, aluminum, PVC, cast iron, bronze, and more.
Design: The drills feature CBN ground flutes for quiet operation and high cutting performance. A cone at the end facilitates easy withdrawal from materials.
Sizes: The document lists various sizes of drills, specifying diameter ranges (Ø1 - Ø2), length (L1), and additional diameter (Ø3).

Procedures:

CBN Ground Flutes: These ensure burr-free, sharp cutting edges, enhancing cutting performance and tool life.
Relief Angle: The relief angle on the underside aids in easy removal from materials.

Cutting Speeds:

The document provides a table of cutting speeds for different materials and drill sizes, specifying the recommended revolutions per minute (r.p.m.) for each material type and drill size.
Materials Covered: High carbon structural steel, alloyed steel, cast iron, CuZn-alloys, aluminum alloys, thermoplastics, and duroplastics.

Recommendations:

Use cutting spray or air as a cooling lubricant depending on the material being drilled.
Follow the specified cutting speeds to ensure optimal performance and tool longevity.

The relief angle on the underside of the tool enables easier removal from the material. Packaging: plastic tubes Product information1. CBN ground flute Thanks to the CBN deep-ground flutes, the cutting edges are burr-free and sharp in contrast to the conventional milled flutes. This results in a significantly higher cutting performance and a much longer tool life. Thanks to the radial CBN relief grinding, the cutting edge is clearly the highest point in the diameter.
