Seco 03080508 Indexable Insert Drill 7/8 Inch 3xd

Product Description

The SECO 03080508 is a straight-shank indexable insert drill from the PerfoMAX series, engineered for general-purpose drilling in metal cutting applications. It accepts two indexable inserts and delivers a maximum drill depth of 66.80 mm at a 3xD depth-to-diameter ratio. The drill diameter is 7/8 inch (0.8750 inch decimal), and the shank diameter is 1 inch. Coolant-through capability supports chip evacuation and thermal management during production drilling. The tool body is constructed from steel and is designed for right-hand cutting. This drill is intended for use by machinist professionals in CNC turning centers and machining centers where insert-based tooling is standard.

The 03080508 suits general-purpose drilling in medium-to-high volume production environments. Its 3xD ratio makes it well matched for through-hole and blind-hole operations in steel and similar workpiece materials. The straight cylindrical shank and 1-inch shank diameter allow direct mounting in standard toolholders without additional adapters in many setups. Compatible insert styles include SCGX and SPGX, and the compatible insert size codes are 060204 and 0703, with SPGX0703 confirmed as a compatible insert. The modular connection size is R7-C.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the tool changer or turret must be in a safe, locked position before mounting or removing the drill body. Follow the toolholder manufacturer torque specifications for the clamping interface, and confirm insert seating and screw torque per the insert supplier guidelines before cutting. Verify coolant-through passages are clear and connected before initiating the first cut.
