Value Collection SC1630C Indexable Center Drill 5/8 in

Product Description

The VALUE COLLECTION SC1630C is an indexable center drill designed for precise center-hole spotting and chamfering operations on metalworking lathes, mills, and machining centers. Built around a replaceable insert system using SC1630C-style inserts, this tool eliminates the need to replace the entire drill body when the cutting edge wears. The body measures 4.5 inches overall length with a 5/8-inch diameter, and the included insert geometry is ground to a 118-degree included angle — the standard for general-purpose center drilling in steel, cast iron, and aluminum. Total tool weight is 0.3 pounds.

This center drill is suited for production and job-shop environments where machinists need consistent, repeatable center holes before turning between centers or before drilling operations to prevent walking. The indexable insert design reduces downtime compared to solid high-speed steel center drills. Typical applications include lathe center-hole preparation, chamfering, and spotting on CNC turning centers and manual lathes across a range of ferrous and non-ferrous workpiece materials.

Key Features

• Indexable insert design accepts SC1630C inserts for fast edge replacement without removing the tool holder
• 118-degree included angle suits general-purpose center drilling and chamfering
• 5/8-inch body diameter with 4.5-inch overall length for reach in standard tooling setups
• Lightweight at 0.3 pounds, reducing spindle load on smaller machines
• Insert-based system lowers long-term tooling cost versus solid carbide or HSS center drills

Compatibility

Designed for use with SC1630C indexable inserts. Fits standard tooling setups on CNC turning centers, manual lathes, and vertical machining centers that accept 5/8-inch shank or body diameter center drill tooling.

Installation Notes

Installation and insert indexing should be performed by a qualified machinist with the spindle powered down and locked out per facility LOTO procedures. Secure the insert with the manufacturer-specified retention screw and confirm seating before running. Inspect the insert pocket for chips or debris before indexing to a fresh edge. Follow your machine tool manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
