Product catalog summary

Product Overview

The EF-Drill Modular is a German-engineered modular twist drill system designed for large diameter holes (14 to 32 mm) primarily in steel and cast materials, with additional use in stainless steels and aluminum alloys. It complements the existing EF-Drill range covering smaller diameters (2.8 to 16 mm).

Key Features

Exchangeable Solid Carbide Cutting Heads: Enhanced cutting edge geometry for improved self-centering and high drilling accuracy, suitable for drilled tap holes and cold-forming threads.
Modular Design: One holder per millimeter diameter range enables flexible use of cutting heads with different diameters and geometries, reducing tooling costs compared to solid carbide drills.
Patented Interface: Form- and force-fit connection with face screw fasteners ensures secure, high-performance machining and easy cutting head changes, even during operation.
TIALN-T21 Coating: Provides high temperature resistance, reduces built-up edge and adhesion wear, minimizes chipping, and extends tool life significantly.
Optimized Coolant Supply: Coolant holes direct fluid precisely into the cutting zone, enhancing chip evacuation and cooling efficiency.
Flute Design: Engineered for excellent chip removal while maintaining tool stability.

Application Areas

Optimized for large diameter drilling in:

Various steel grades including cold-extrusion, construction, free-cutting, cementation, heat-treatable, and high-alloy steels (up to 1400 N/mm² tensile strength).
Stainless steels (ferritic, martensitic, austenitic, duplex, super duplex) with tensile strengths up to 1250 N/mm².
Cast irons (lamellar, nodular, vermicular graphite, malleable cast iron).
Non-ferrous materials such as aluminum alloys, copper alloys, magnesium alloys, plastics, and composites.
Special materials including graphite, tungsten-copper alloys, titanium alloys, nickel, cobalt, iron-based alloys, and hardened steels up to 66 HRC.

Suitability and Cutting Data

Material suitability is indicated by symbols: $ for very suitable and ) for suitable. Detailed cutting speeds (vc in m/min) and feed per revolution (f in mm/rev) are provided in the full technical data (page 6 of the original document), tailored for different materials and machine capabilities.

Coolant and Lubrication Recommendations

The system supports emulsions, oils, minimum quantity lubrication (MQL), dry machining, and pressurized air. The coolant supply design enhances machining performance and chip evacuation efficiency.

Benefits and Best Practices

Modular system reduces tooling inventory and costs by reusing holders with different cutting heads.
Patented interface allows secure and quick cutting head changes during machining.
TIALN-T21 coating extends tool life by minimizing wear.
Optimized coolant delivery and flute design improve machining stability and chip removal.
Wide material compatibility ensures versatility across diverse industrial applications.

Material Specifications

Titanium Alloys: Pure titanium (≤ 450 N/mm²), TiAl6V4 (≤ 900 N/mm²), TiAl4Mo4Sn2 (≤ 1250 N/mm²).

Cutting Data and Recommendations

Cutting speeds are provided as minimum, recommended (bold), and maximum values to suit different machines and workpiece conditions.
Recommended values target stable conditions and high-performance machines with adequate spindle speed.
Lower speeds with higher feeds suit machines with lower spindle speeds.
Maximum speeds with reduced feeds apply to optimal conditions and very high-speed machines.

Tool Specifications and Ordering Information

Solid carbide cutting heads designed for steel and cast iron with two flutes and two margins, 140° point angle.
Various diameters with corresponding insert seat sizes and tool IDs.
Ordering examples specify cutting head type, geometry, flute count, margins, and point angle.

Tool Body and Dimensions

Tool bodies for drill depths of 3xD and 5xD comply with DIN 6535 standards (HA and HE types), with diameter ranges, insert seat sizes, and lengths (l1, l2, l3, l4) detailed. Tolerance classes IT9-IT11 apply.

Accessories

Screwdrivers and clamping screws for insert seats are specified with sizes, blade diameters, torque values, and article numbers.
Delivery includes Torx screws but excludes solid carbide cutting heads.
