COGSDILL BURR-OFF DEBURRING TOOL

Product Overview

The Cogsdill Burr-Off® is an automated, high-production deburring tool designed to deburr the front, back, or both sides of a hole in one fast pass. Operating on a similar basic principle to the Burraway® system, the Burr-Off features an open-slot "clothespin tool" design that allows chips to clear easily, making it ideal for automatic equipment and multi-spindle machines.

The tool utilizes a simple one-piece construction with integral cutting edges. Models CP-20 through CP-40 are supplied with a drive tang on the shank.

Key Features & Capabilities

Single-Pass Deburring: Cleans and deburrs the front, back, or both sides of a hole in a single continuous stroke.
Open-Slot "Clothespin" Design: Slotted design allows the tool to "collapse" under load as it feeds through the workpiece, ensuring easy chip clearance for high-volume automated and multi-spindle environments.
Surface Protection: Features a crowned and polished top surface on the cutting edges that will not mar the inside surface of the hole.
Adjustable Tension: Equipped with a sliding tension-adjustment mechanism (on all models except CP-4 through CP-9) to control the amount of edge break and stock removal based on material hardness.
Cutting Edge Configuration:
CP-4 through CP-13: Feature a single cutting edge for hole sizes from .062 inch (1.57 mm) through .219 inch (5.56 mm).
CP-14 and Larger: Feature two cutting edges.
Resharpening Capability: Cutting edges may be reground up to four times to extend tool life.

Operating Recommendations

Speeds and Feeds: Run using the same speed and feed rates as a standard high-speed steel (HSS) drill.
Edge Break Adjustment: Loosen the screw on the sliding tension-adjustment mechanism and move it up or down the length of the slot to increase or decrease stock removal.
Resharpening Procedure: Hand grind the face .010–.015 in. (0.25 mm–0.38mm), preferably using an abrasive wheel matching the specified "A" diameter. Flat face grinding is optional.
