How to Choose a Glass Cutter

Features of Glass Cutters

Our high-performance glass cutters can be widely used across various glass materials and thicknesses, from FPD and construction materials to automotive and hobby applications. It is also possible to inject oil into the cutter body for glass cutting. By using oil, it permeates the cutting line, preventing glass debris from scattering and improving the quality of the glass cutting surface.

The glass cutter products from Mitsuboshi Diamond Industrial Co., Ltd. are of high quality and reliability, meeting diverse needs. For specific product selection, please refer to the guide below to research the product models.

Names of Parts	Detailed Information
1.Cutting Edge	The cutting edge specifications come in four types (Micro Penett®, Penett®, APIO®, Normal Wheel) depending on thickness and intended use.
2.Holder/Holder Slim Type	The holder is designed for straight cuts (handles: M15, M17, M19) and a slim type for curved cuts (handles: M16, M18, M20).
3.Coupler	By twisting the coupler (handles: M17, M18) to inject oil, it allows the oil to permeate the cutting edge, preventing glass debris from scattering.
4.Handle	Three types of durable and comfortable-to-hold designs are available (handles: M15/M16, M17/M18, M19/M20).
5.Cap Screw	The cap screw (handles: M15, M16, M19, M20) can be twisted to allow for oil injection.

(Names of Parts of Glass Cutter Products)

Our glass cutters are designed with a mechanism that allows oil to seep out to the cutting edge during scribing. (Please prepare the oil yourself.)

How to Choose a Glass Cutter

Glass Thickness (mm)	Cutting Edge Wheel Type	Cutting Edge Characteristics	Plate Thickness (Specifications) ¹	Cutting Edge Material	Cutting Edge Material Characteristics	Handle Type	Holder
0.05～0.4	Micro Penett®	It is possible to extend deeper vertical cracks compared to Normal Wheel and APIO.	S	PCD	D: Polycrystalline Diamond (PCD) sintered diamond offers a long lifespan. C: Tungsten carbide is more cost-effective compared to sintered diamond.	The standard types are M17 and M18, which are long-handle types, and there are also cap screw types available (M15, M16, M19, M20).	There are two types: Normal and Slim. The Slim type is recommended for curved cutting due to its excellent maneuverability.

(Examples of How to Choose)

Choose the “Cutting Edge” and “Plate Thickness (Specifications)” based on the glass thickness to be cut and the characteristics of the cutting edge.
Next, select the “Cutting Edge Material” based on the characteristics of the cutting edge material.
Finally, choose the “Handle Type” and “Holder.”

Caution

Recently, there has been an increase in counterfeit versions of our glass cutter products circulating in the market. These imitation products do not meet quality standards and may cause malfunctions in the equipment. To avoid accidental purchases, please ensure that you buy only from authorized dealers.
