Seco 03079566 Indexable Insert Drill 20.62mm 5xd

Product Description

The SECO 03079566 is a straight-shank indexable insert drill from the PerfoMAX series, designed for high-productivity hole-making in metalworking applications. It accepts two indexable inserts in compatible styles SCGX and SPGX, allowing insert rotation or replacement without removing the tool body from the machine. The drill body is constructed of steel and features a 1-inch straight-cylindrical shank with a 5xD depth-to-diameter ratio, achieving a maximum drill depth of 103.12mm at a cutting diameter of 20.62mm. Coolant-through capability supports chip evacuation and heat control at depth. Right-hand cutting direction is standard. This tool is installed and operated by machinists and CNC tooling technicians in production and job-shop environments.

The 03079566 is suited for general-purpose drilling operations in ferrous and non-ferrous materials where a consistent, repeatable hole diameter near 20.62mm is required. Its modular R7 connection size and straight shank make it compatible with standard toolholders and spindle setups found on machining centers and CNC lathes. The 5xD ratio targets applications where moderate depth-to-diameter performance is needed without specialty deep-hole equipment. Two-insert construction distributes cutting load and supports balanced chip formation across the drill face.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. Confirm spindle and toolholder are powered down and fully stopped before mounting or removing the drill body. Verify insert seating and fastener engagement per toolholder manufacturer guidelines before initiating a cut. Coolant-through lines should be confirmed open and at rated pressure before drilling at full depth to prevent chip packing and premature insert wear.
