Seco 02445823 Replaceable-tip Drill 17-17.99mm SD100

Product Description

The SECO 02445823 is a replaceable-tip drill designed for precision hole-making in metal cutting and machining applications. It accepts SD100 series inserts, allowing the cutting tip to be swapped out without replacing the entire tool body. The drill covers a diameter range of 17 to 17.99 mm (0.6693 to 0.7083 inches) and reaches a maximum drill depth of 1.18 inches. A through-coolant design channels fluid directly to the cutting zone, helping to extend insert life and clear chips efficiently. The 3/4-inch Weldon flat shank provides positive drive with minimal runout in compatible holders.

This drill is suited for production and job-shop CNC machining environments where consistent hole geometry and fast cycle times are priorities. It is a good fit for milling centers and drill presses equipped with Weldon-style toolholders. The SD101 series toolholder body pairs with SD100 inserts, making this a modular system that reduces tooling inventory cost. Machinists working in aerospace, automotive, and general fabrication shops will find the through-coolant feature particularly useful when drilling steel, stainless, and cast iron at elevated feed rates.

Key Features

• Replaceable SD100 insert tip — change the cutting edge without replacing the drill body
• Through-coolant design delivers fluid directly to the cutting zone for chip evacuation and thermal control
• Diameter range of 17 to 17.99 mm accommodates a range of close-tolerance hole sizes
• 3/4-inch Weldon flat shank provides secure, positive drive in standard Weldon-style holders
• SD101 series body with 4.61-inch overall length suits a wide range of spindle clearance requirements
• Flute length of 0.65 inches and body length of 2.409 inches support rigid, low-deflection drilling

Compatibility

Compatible with SD100 series replaceable drill inserts. Designed for use with SD101 series toolholder bodies. Requires a Weldon flat toolholder with a 3/4-inch bore.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before mounting, confirm the spindle and toolholder are de-energized and the machine is in a locked-out state per shop lockout/tagout procedures. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to the toolholder manufacturer's specification. Verify through-coolant ports are clear and coolant pressure is within the machine spindle's rated range before starting the cut.
