Product catalog summary
Company Overview: EMUGE, part of the EMUGE-FRANKEN group, specializes in precision tools for thread production and clamping of tools and workpieces. Their product range includes taps, cold-forming taps, thread milling cutters, twist drills, dies, and thread rolls, all designed to enhance productivity and quality.
Product Lines: EMUGE offers a comprehensive range of solid carbide twist drills under the EF-Drill brand, categorized into four main product lines: EF-Drill Micro, EF-Drill, EF-Drill Modular, and EF-Drill C. Each line is tailored for specific applications, with varying diameter ranges and features such as internal cooling and specialized coatings.
EF-Drill Micro: Designed for small drill holes with a diameter range of 0.75 to 3.00 mm, featuring internal cooling and TIALN-T99 coating, suitable for ISO material groups P, M, K, N, S.
EF-Drill: Available in STEEL, VA, GG, and HCUT geometries, with a diameter range of 2.80 to 20.00 mm, offering both external and internal cooling options, and suitable for various ISO material groups.
EF-Drill Modular: Features a modular design with exchangeable cutting heads, covering a diameter range of 14.00 to 32.00 mm, providing flexibility and cost efficiency.
EF-Drill C: A chamfer drill with a diameter range of 2.80 to 15.50 mm, designed for economical production by combining drilling and chamfering in one step.
Technical Specifications: The catalogue provides detailed specifications for each drill type, including tool features, application areas, and recommended coolant-lubricants. It also includes a comprehensive guide on article code numbers, ordering examples, and technical information to assist in product selection and usage.
Technical Specifications and Recommendations: The document provides technical specifications and recommendations for cutting speeds and feed rates for various machine tools and workpiece conditions. It includes detailed tables with cutting speed (vc) and feed per revolution (f) values for different drill diameters and materials.
Specifications: Cutting speed and feed rate values are outlined for different drill diameters (D = 3 mm to D = 20 mm) and materials (Steel, VA, GG, HCUT). Minimum, recommended, and maximum values for both cutting speed and feed per revolution are provided.
Procedures: For optimal workpiece conditions and high-performance machine tools, high cutting speeds with reduced feed values are recommended. For machines with lower spindle speeds, lower cutting speeds with higher feed values should be used.
Recommendations: Use bold printed standard values for stable work conditions and high-performance tools. For EF-Drill-STEEL 8 x D, preparatory centering with a pilot drill is advised, and the feed per revolution should be reduced by 15%.
Key Data from Tables: The tables provide specific cutting speed and feed rate values for different materials and drill diameters. For example, for Steel with a 3 mm diameter drill, the recommended cutting speed is 120 m/min, and the feed per revolution is 0.11 mm/rev.
EF-Drill Tools for Steel: This section provides technical specifications and recommendations for EF-Drill tools, specifically designed for steel materials. It includes detailed dimensions, applications, and tool identifications for various drill sizes and types.
Specifications: Drill Depth: 8xD for steel materials. Tool Identification: Example ID - TA223344. Drill Types: Includes taps and cold-forming taps with specific dimensions and identifications. Material Applications: Suitable for various steel grades (P 1.1-5.1, M 1.1, K 1.1-4.2, N 1.1-5, N 2.1-8).
Procedures: Preparatory Centering: Recommended using a centering drill, such as EF-Drill acc. DIN 6537 K. Ordering Example: TA223344.0950 for drills ranging from ø 2.80 mm to ø 9.45 mm.

Assembly Instructions: Instructions for assembling the drill head into the holder are provided. This includes inserting and tightening screws with recommended torque values, which vary based on the size of the insert seat.
Machining Conditions: Guidelines for machining conditions are outlined, emphasizing the preference for internal cooling and specifying a recommended coolant-lubricant pressure of over 20 bar. The document also notes the maximum allowable slant for entry and exit, axle offset, and run-out.
Problem Solving: The document addresses common drilling problems such as excessive wear, chipping, and coating issues. It lists possible causes like excessive feed, high friction, and unstable clamping, along with solutions such as adjusting feed rates, improving clamping, and using lubricants with higher oil content.
Technical Questionnaire: A technical questionnaire is included for solid carbide twist drills, requesting information about the company, contact details, drill specifications, machining conditions, and previous tool usage.
General Overview: This document outlines the general sales conditions and tool identification numbers for a supplier's products. It includes terms related to delivery, risk transfer, ownership retention, defect claims, and legal rights.
Delivery Conditions: Delivery times may be extended due to force majeure or events beyond the supplier's control. The supplier must inform the buyer of such delays.
