The Cimco twist drill assortment, type 201352, includes 19 individual drills made of high-speed steel (HSS-R/HSS-PG), manufactured according to DIN 338 standard. The drills are roll-formed and available in a diameter range from 1 mm to 10 mm, with diameters increasing in 0.5 mm increments. The assortment is delivered in a highly stable plastic cassette equipped with clamping strips for each drill, ensuring secure and organized storage. These drills are suitable for drilling in metal, particularly in steel and other ductile materials, and are designed for use in hand drills as well as machine tools.

Applications
This assortment is designed for applications in metalworking, particularly for drilling in steel, aluminium, and other metallic materials. The drills are suitable for use in workshops, machine building, assembly, and craft trades, where high precision and tool longevity are required. The combination of HSS material and roll-formed manufacturing enables high tool life and reliable drilling performance at medium to high speeds.

Functions and Equipment in Detail
The drills are made of HSS-R/HSS-PG steel, a tool steel with high heat resistance and wear resistance. The roll-formed manufacturing process ensures a uniform surface structure and improves cutting performance. The drills are available in a diameter range from 1 mm to 10 mm, with each drill differing by 0.5 mm. The cassette provides space for all 19 drills and is equipped with clamping strips to securely fix each tool and protect against shifting or damage.

Technology Explained Simply
The designation HSS-R/HSS-PG refers to high-speed steel, specifically developed for tools used under high temperatures and loads. The roll-formed manufacturing means the drills are produced by a rolling process, resulting in a smoother surface and improved mechanical properties. The DIN 338 standard defines the geometric and technical requirements for twist drills, including cutting edge shape, cone angle, and tolerances. Therefore, the drills are suitable for standardized use in various machine tools and drilling devices.

Compatibility and Accessories
The drills are designed for all drilling machines that accept twist drills with DIN 338 geometry. They are compatible with standard drill chucks and clamping devices. The cassette serves as storage and transport container, with clamping strips ensuring the drills do not shift or get damaged during transport.

Mounting and Installation
The drills are directly clamped into the drill chuck of the machine. The cassette serves only for storage and organization. No additional mounting or installation is required. The drills are immediately ready for use once removed from the cassette and clamped into the drill chuck.

Advantages in Operation
The roll-formed manufacturing and use of HSS-R/HSS-PG steel ensure high tool life and consistent drilling performance. The precise tolerance according to DIN 338 guarantees high accuracy of the drilled holes. The cassette enables clear and secure storage, protecting the tools from damage and ensuring quick access. The assortment design with 19 drills in 0.5 mm increments provides broad coverage for various drilling tasks without requiring additional tools.
