Esko Kongsberg 3mm Multi-Purpose Up Cut Down Cut Milling & Router Bits

These bits are designated under Esko's MUS (Multi-Purpose Up-Cut Single-Flute) and MDS (Multi-Purpose Down-Cut Single-Flute) codes. The 3mm shank and 38mm total length format is explicitly engineered for compact, precise routing. They are most commonly used on smaller-format tables or specialized to… Inquiry Now

Description

Esko Kongsberg 3mm Multi-Purpose Up Cut Down Cut Milling & Router Bits

1. Multi-Purpose Up-Cut Single-Flute (BIT-MUS03-...)

Up-cut geometry pulls chips upward out of the cut. These are preferred for materials prone to melting (plastics) or where deep channel clearing is needed to prevent heat buildup.

Part Number	Esko OEM Code	Shank (D)	Tip Dia. (d)	Flute Length (M)	Total Length (L)	Primary Applications
BIT-MUS03-1004-38	G42443390	3 mm	1.0 mm	4 mm	38 mm	Extremely fine detail engraving, micro-lettering, and intricate plastic prototyping.
BIT-MUS03-1506-38	G42443408	3 mm	1.5 mm	6 mm	38 mm	Tight-radius filigree profiling on thin plastics and dense cardboards.
BIT-MUS03-2006-38	G42443416	3 mm	2.0 mm	6 mm	38 mm	Standard detail pocketing and precise channel routing in thin rigid materials.
BIT-MUS03-2506-38	G42443424	3 mm	2.5 mm	6 mm	38 mm	Intermediate-step profiling balancing fine corner detail with rigidity.
BIT-MUS03-3006-38	G42443432	3 mm	3.0 mm	6 mm	38 mm	Balanced high-speed cutting on thin sheets where a 1:1 shank-to-tip ratio maximizes strength.
BIT-MUS03-3011-38	G42443440	3 mm	3.0 mm	11 mm	38 mm	Maximum depth profiling for 3mm tools, ideal for sheets up to 9mm thick.

2. Multi-Purpose Down-Cut Single-Flute (BIT-MDS03-...)

Down-cut geometry pushes material fibers and chips downward. These are the industry standard for securing delicate top layers and preventing thin foils or laminates from peeling upward.

Part Number	Esko OEM Code	Shank (D)	Tip Dia. (d)	Flute Length (M)	Total Length (L)	Primary Applications
BIT-MDS03-1002-38	G42449306	3 mm	1.0 mm	2 mm	38 mm	Shallow engraving on foil-laminated cartons or thin plastic plates without lifting edges.
BIT-MDS03-1503-38	G42449314	3 mm	1.5 mm	3 mm	38 mm	Delicate top-surface engraving and clean scoring on thin multi-layer composites.
BIT-MDS03-3006-38	G42449330	3 mm	3.0 mm	6 mm	38 mm	High-speed profiling of thin laminates where a chip-free top edge is required.
BIT-MDS03-3011-38	G42449348	3 mm	3.0 mm	11 mm	38 mm	Deeper cutting on veneered or laminated surfaces up to 9mm thick.

Intended Material Capabilities

Because these are Multi-Purpose bits, they feature balanced rake and clearance angles designed to handle a wide range of soft and medium-rigid substrates:

Thin Plastics: Acrylic, Polycarbonate, PETG, and PVC.

Packaging Materials: Solid paperboard, heavy folding carton, dense foam-core boards, and structural corrugated plastics (Coroplast).

Soft Composites: Thin aluminum skins bonded to polymer cores (lightweight ACM/Dibond layouts).
