Product Overview
Small Dia of Deep hook flat End mill : small-diameter, long-reach (deep hook/pocket) coated solid carbide
flat-bottom end mill (commonly referred to as a micro-diameter
long-neck flat end mill). It represents a high-end cutting solution
in the fields of precision micro-machining and mold manufacturing,
purpose-built to tackle high-aspect-ratio workpiece features such
as deep narrow slots, steep vertical shoulders, and deep-seated
blind cavities.
Key Features & Advantages
Micro-Diameter Cutting Geometry: Featuring an ultra-small cutting diameter, this tool is perfectly
capable of handling intricate engraving, high-precision narrow
slotting, and miniature electronics component milling.
Tapered Long-Neck Configuration: Engineered with an extended neck clearance that progressively
thickens towards the shank (reinforced tapered neck structure).
This layout allows the tool to submerge safely into narrow, deep
cavities to avoid shank-workpiece collision while retaining maximum
base rigidity.
Superior Rigidity & Anti-Chipping Design: Manufactured from premium micrograin or ultra-fine grain solid
carbide (tungsten steel). To eliminate tool deflection ("tool
push") and premature breakage common to long-reach micro-tools, the
core web thickness and neck taper are strictly optimized to
suppress vibration and chatter.
Advanced Nano-Composite Coating: The cutting zone and neck are protected by a premium
bronze/copper-colored thermal-barrier coating (such as TiAlN/AlTiN
nano-composite). This coating provides exceptional red-hardness and
a low friction coefficient, shielding the miniature cutting edge
from severe thermal wear during high-speed, dry-milling cycles.
Precision-Ground Helical Flutes: The flute profiles are meticulously ground to ensure a smooth
finish. This facilitates rapid and unobstructed evacuation of
microscopic chips from deep-seated channels, preventing chip
re-cutting and ensuring an ultra-smooth workpiece surface.
Typical Applications
Machining Operations: Deep cavity side-milling and bottom-finishing alongside steep
vertical walls, deep slotting (deep hook applications), 3D
micro-milling for electromechanical components, and deep-set
counterbore cleaning.
Applicable Materials: Benefiting from the premium carbide substrate and advanced coating
synergy, it is highly optimized for:
Mold Steels, Pre-Hardened Steels, and High-Hardness Quenched Steels (Capable of machining materials up to HRC 55-65)
Stainless Steels, Alloy Steels, and Carbon Steels
High-precision hardware components and difficult-to-machine
heat-resistant alloys.
