R570 Solid Carbide High Performance CDX-DH Drill
for Deep Hole Drilling

• Deep drilling in “one hit” to 8 x diameter - no pecking required - reduction in machining time.
• Fast and efficient chip evacuation leading to high productivity and reduced cost per hole.
• High quality finish, good hole tolerance.
• Consistent forces.
• Improved tool life leading to a reduction in machine downtime.
• Exceptional levels of performance in steel, stainless steel, cast iron, copper, aluminium and other materials.

MATERIAL Micrograin carbide. HOLE DEPTH: The extra length enables drilling depths of up to 8 x D to be achieved without the need for pecking throughout the full diameter range of 3mm – 12mm and 17/64” – 5/8”. Further incremental sizes and sizes for drilling up to 12 x Diameter are available on request. ACM™ FLUTE GEOMETRY: Dormer’s ACM™ (Advanced Chip Management) flute geometry optimises flute volume and breaks the chips into small, manageable pieces to ensure efficient chip evacuation in deep hole applications, reducing machine downtime. ACM ensures consistent forces throughout the drilling cycle. COATING: The new Super-Flow coating has been developed to optimise performance of the CDX-DH drill, offering: • Specialist surface treatment to assist chip evacuation. • Greater stability of cutting edges • Outstanding wear resistance • High hardness and toughness properties and oxidation stability • Exceptional chip evacuation capabilities on all recommended materials. Tool life and productivity are significantly increased as a result of the new Super-Flow coating. COOLANT: Internal coolant holes ensure that coolant is delivered directly to the tip of the drill, cooling the cutting area and efficiently evacuating the chips from the hole. This allows for high feeds and speeds, resulting in high productivity and lower cost per hole. POINT DESIGN: Specially designed 140º point allows for excellent centring and ensures that thrust force is low. Downlod the Brochure
