Características para DSW
1. Nueva calidad de recubrimiento con mayor resistencia al desgaste
• Nueva calidad de metal duro con recubrimiento de gran versatilidad. Calidad perfecta para una durabilidad estable y prolongada de la herramienta en una amplia gama de materiales.
2. Su innovadora arista de corte ofrece un taladrado fiable
• La forma no convencional de la arista reduce las fuerzas de corte y mejora la fuerza de adherencia del recubrimiento para evitar la rotura repentina de la arista.
3. Estilo de mango estándar en todo el mundo – Estandarizado con DIN6535-Forma HA
• Sólo 6 diámetros de mango disponibles: ø6, ø8, ø10, ø12, ø14, ø16 mm. Esto reduce el número de mordazas necesarias.
Características para DSM
1. Variedad de medidas y L/D
• Permite realizar agujeros profundos de hasta 5 a 15 veces el diámetro de la broca.
• Disponibles como artículos estándar de ø0,1 a ø3,0 mm en incrementos de 0,01 mm. Los diámetros de mango están unificados a ø3 mm.
2. Brocas de centrado para el mecanizado del agujero guía
- El tipo DSM-CP140 tiene un ángulo de punta de 140° que puede evitar eficazmente que la arista de corte se astille.
- El tipo DSM-CP90, que tiene un ángulo de punta de 90°, también puede utilizarse para chaflanar la boca del agujero.

- The cutting parameters shown in the table are merely a starting guideline for general machining. Values should be varied depending on the power or rigidity of the machine to be used. Optimum conditions should be selected depending on the actual chip control or damage on edges.
- When using the smaller diameter tools in each range, set the feed “f” to the lower recommended values.
- The coolant supply is critical for the provision of stable machining conditions and enhanced tool life. A large coolant volume should be supplied, especially when drilling di! cult-to-cut materials.
- When drilling stainless steel with low machinability such as austenitic stainless steel with a depth deeper than L/D = 3, a pecking cycle or internal coolant supply is recommended.
