G83 Deep Hole Peck Drilling Canned Cycle Programming

G83 is a canned cycle for deep-hole drilling that repeatedly feeds into the material by an incremental peck depth (Q) and retracts completely to the initial plane (R) to evacuate chips and deliver coolant.

Engineering Specifications & Parameters

Cycle Name	Deep Hole Peck Drilling Cycle
G73 Motion	Micro-Retract (Chip Breaker Only)
G83 Motion	Full Retract to R-Plane
Standard Depth Ratio	> 3x to 10x Tool Diameter

Canned Cycle Format

G98 G83 X25.0 Y30.0 Z-40.0 R2.0 Q5.0 F120

Z: Final drilling depth.
R: Retract clearance plane above part.
Q: Peck incremental depth per step.
F: Feed rate.

G83 vs G73

G83 (Full Retract): Clears chips completely out of the hole; mandatory for hole depths > 3x diameter.
G73 (Chip Break): Retracts only 0.5-1.0mm to break stringy chips in shallow holes.

Frequently Asked Questions

When should you use G83 instead of G81 standard drill?

G81 does not peck; G83 is required when drilling deeper than 3 times the drill diameter to prevent chip packing and drill breakage.
