Value Collection SC2182132 Countersink 1-1/2 in 6 Flute

Product Description

The VALUE COLLECTION SC2182132 is a single-end cobalt steel countersink designed for deburring and seat-cutting operations in metal fabrication and machining applications. With a 1-1/2 inch head diameter and an 82-degree included angle (41-degree centerline angle), it produces clean, accurate countersunk profiles for flat-head fasteners. The six-flute geometry distributes cutting load evenly, reducing chatter and extending tool life in harder workpiece materials. The bright, uncoated finish suits general-purpose countersinking without added coating thickness. Machinists and toolroom technicians are the primary users of this tool.

This countersink is suited for use in manual machining centers, drill presses, and CNC equipment where precise countersink geometry is required. The straight cylindrical 3/4 inch shank accepts standard tool holders and collet chucks. Right-hand cutting direction is standard for conventional spindle rotation. The 82-degree angle matches the seating geometry of most imperial flat-head machine screws and aerospace-style fasteners. No pilot is included, so a separate pilot or starting hole is required before use.

Key Features

• 1-1/2 inch head diameter for large-diameter countersink seats
• 82-degree included angle matches standard flat-head fastener seating geometry
• 6-flute design reduces chatter and promotes smooth cutting action
• Cobalt steel construction provides heat and wear resistance in harder materials
• 3/4 inch straight cylindrical shank fits standard collet chucks and tool holders
• Bright/uncoated finish — no coating tolerance buildup at cutting edges

Compatibility

Designed as a general-purpose countersink for use in drill presses, manual mills, and CNC machining centers equipped with a 3/4 inch collet or tool holder capable of accepting a straight cylindrical shank.

Installation Notes

This tool is installed and used by machinists and toolroom professionals. Secure the shank fully in a properly sized collet or chuck before operation and verify runout is within acceptable limits. Pre-drill a pilot hole to the required minor diameter before engaging the countersink. Follow machine tool manufacturer guidelines for spindle speed selection based on workpiece material and tool diameter.
