Product Description

GEM-GUMD Modular Drill Description
On the one hand, long, multiple-diameter drill bodies have high requirements for chip removal performance. To enhance the chip removal of the drill body, we adopted a large chip flute design. On the other hand, long multiple diameters have high requirements for the rigidity of the drill body. Therefore, we used high-rigidity drill body materials to improve the stability of the drill body during processing.

GEM-GUMD Modular Drill Specification
The GEM-GUMD modular drill series offers high-performance drilling with flexible depth capabilities and internal coolant efficiency, ensuring optimal performance across various applications. Below are the key specifications for each model:

Drills Series	Dimension Range	Coolant Type	Drilling Depth L/D
GUMD-3D	10~21.9mm	Internal Coolant	3D
GUMD-5D	10~21.9mm	Internal Coolant	5D

GEM-GUMD Modular Drill  Features
Suitable for drilling holes in steel, cast iron, and stainless steel ranging from φ10.0mm to φ21.9mm, with depths up to 5D.
High-precision interface and easily replaceable cutter heads.
High-strength drill tip design for excellent centering performance.
Comparison Of The Cutting Life Of Competitors
The data demonstrates a 20% longer tool life for GME products compared to the competitor. With an average lifespan of 30 units, GME significantly outperforms the competitor's 25 units, highlighting superior durability and cost-efficiency. This advantage makes GME the ideal choice for applications demanding extended tool performance and reduced replacement frequency.
