Sandvik Coromant 6085550 Replaceable-tip Drill 8xd

Product Description

The SANDVIK COROMANT 6085550 is a replaceable-tip drill body from the CoroDrill 870 series, designed for precision hole-making in metalworking and machining applications. It accepts 870-1990-19-PM insert tips at seat size 19, covering a drill diameter range of 19.00 to 19.99 mm (0.7480 to 0.7870 inches). The body is constructed from steel and features a straight-cylindrical shank with an overall length of 242 mm (9.5276 inches). Through-coolant delivery is built in, supporting high-feed drilling operations where heat and chip evacuation are critical factors. This drill body is installed by CNC machinists and tooling technicians in production shop environments.

The 6085550 is suited for deep-hole drilling at an 8xD depth-to-diameter ratio, reaching a maximum drill depth of 162.96 mm (6.4158 inches). It fits the 870 LX-8 toolholder style and is appropriate for use on CNC machining centers, lathes with live tooling, and dedicated drilling machines in both job-shop and high-volume production environments. The through-coolant feature makes it well matched for stainless steel, alloy steel, and other materials that generate significant heat during drilling operations.

Key Features

• Replaceable-tip design accepts 870-1990-19-PM inserts at seat size 19, reducing tooling cost versus solid drills
• 8xD depth-to-diameter ratio allows drilling up to 162.96 mm (6.4158 inches) deep in a single pass
• Through-coolant construction supports effective chip evacuation and thermal control at depth
• Straight-cylindrical shank for straightforward clamping in standard ER or hydraulic chuck systems
• 870 LX-8 toolholder style for direct compatibility with Sandvik Coromant modular tooling interfaces
• Steel body construction provides rigidity and durability under high-feed conditions

Compatibility

Compatible with 870-1990-19-PM replaceable insert tips at insert seat size 19. Designed for use with the 870 LX-8 toolholder style within the CoroDrill 870 system platform.

Installation Notes

Installation and tool changes should be performed by qualified CNC tooling technicians with the machine powered down and spindle locked per shop safety procedures. Verify insert seating and torque the tip according to the manufacturer tooling documentation before running. Confirm through-coolant passages are clear and coolant pressure is within the machine specification before initiating a drilling cycle. Do not exceed the rated maximum drill depth or diameter range for this body.
