 Deburr Master ®

Deburr Master ^®

• Precision-production for deburring or chamfering holes

• One simple setscrew adjustment controls depth of cut and releases blade for hand replacement

Deburr Master ^® tools are constructed with precision machined, solid tool steel and can be used on machines such as single or multi-spindle drilling machines, lathes, NC machine tools, machining centers as well as hand tools. Each tool is fitted with a replaceable standard blade made of high-speed steel in Double Action (DA), unless otherwise specified.  Special tools and sizes are available. Please submit a blueprint for quotation.

REPLACEABLE BLADES

Each tool is furnished with a standard blade made of high-speed steel in Double Action (DA), unless otherwise specified.

BLADE REPLACEMENT

1. Loosen the setscrew at the rear of the shank.  The blade will drop freely from the arbor.
2. Set the new blade on the pivot within the arbor and then tighten the setscrew to desired adjustment. Do not compress the spring to its solid condition.  The blade will not retract without spring cushions and damage to hole and tool may occur.

BLADE REGRINDING

Blades can be reground 4 to 10 regrinds of 0.010" each. See diagram below.

DEBURRING ON A CROSS-HOLE

When deburring on a cross-hole, special attention must be paid to the relationship of the cross-hole diameter and that of the main bore.

The main bore must be at least three times larger than the cross-hole diameter or the hole will be damaged.  If the main bore diameter is 3 to 12 times that of the cross-hole then a blade with a 45° angle should be used (available by special order). A standard blade can be used if the main bore diameter is more than 12 times that of the cross-hole.

Machining Analysis for Deburr Master ^® Tools

Add dwell time when feeding the tool through the workpiece to be deburred.  The illustration and analysis below are for standard analysis for high-speed steel cutter.
