Seco 02530424 Replaceable-tip Drill Weldon Flat Shank

Product Description

The SECO 02530424 is a replaceable-tip drill from the Crownloc series, designed for precision hole-making in metalworking and machining applications. It accepts tip diameters ranging from 22.00 mm to 23.99 mm (0.8661 to 0.9445 inches) and delivers a maximum drill depth of 175 mm (6.8898 inches), representing a 7xD depth-to-diameter ratio. The 1-inch Weldon Flat shank provides positive rotational drive in compatible toolholders. Overall length is 10.413 inches, and the tool features through-coolant capability with a TiAlN coating for extended tool life in demanding cutting conditions. Licensed machinists and CNC tool-room technicians are the primary installers and operators.

This drill is used in production and job-shop machining environments where consistent, repeatable hole geometry is required across moderate-to-deep bore depths. The replaceable-tip design reduces tooling cost by allowing tip swap-out without discarding the shank body. The through-coolant feature makes it well suited for deep-hole operations in ferrous and non-ferrous materials where chip evacuation and heat management are critical. The SD107 toolholder style designation guides compatible holder selection for setup.

Key Features

• Tip diameter range of 22.00 to 23.99 mm (0.8661 to 0.9445 inches) for flexible sizing within one body
• 7xD depth-to-diameter ratio with a maximum drill depth of 175 mm (6.8898 inches)
• Through-coolant design supports chip evacuation and thermal control in deep-hole applications
• TiAlN coating improves wear resistance and thermal stability at elevated cutting speeds
• Weldon Flat shank with 1-inch diameter provides secure, anti-slip drive in standard holders
• Replaceable-tip construction reduces per-hole tooling cost compared to solid-body alternatives

Compatibility

The 02530424 is designed for use with SD107-style toolholders. It is part of the SECO Crownloc replaceable-tip drill series and accepts tip diameters in the 22.00 to 23.99 mm range.

Installation Notes

Installation and tip changes should be performed by qualified machining personnel with the machine powered down and spindle locked. Ensure the Weldon Flat shank is properly seated and the set screw is torqued according to the toolholder manufacturer's specifications. Verify through-coolant passages are clear before operation. Follow the machine tool builder's guidelines and applicable shop safety procedures when setting depth stops and feed rates.
