Product Design & Threading Performance
Spiral Flute Geometry for Efficient Chip Evacuation
The spiral flute design guides chips upward during blind-hole tapping, helping prevent chip packing around the cutting area. This structure improves tapping stability and reduces the risk of thread damage caused by poor chip removal.
Key Performance Advantages
High Rigidity Solid Carbide Construction
The fine-grain solid carbide body provides higher rigidity and wear resistance compared with conventional HSS taps. The stable cutting structure helps reduce tool deflection and supports consistent thread quality during CNC production.
Stable Thread Accuracy and Surface Quality
Precision-ground cutting edges and controlled thread geometry help maintain accurate internal threads, reduce variation between holes and support applications requiring repeatable production quality.
Flexible Thread Size and OEM Configuration
Different thread standards, sizes, coatings and packaging requirements can be reviewed according to application needs. OEM marking and customized supply solutions are available for distributors and industrial buyers.

FAQ sur les produits et leurs applications
Selection and application guidance for steel milling.
What materials is this HRC55 square end mill designed to machine?
It is primarily configured for carbon steel, alloy steel and confirmed pre-hardened steel applications. The exact coating and cutting parameters should be selected according to the workpiece grade, hardness, machining operation and machine rigidity.
Does HRC55 mean that every tool can machine steel at exactly 55 HRC?
HRC55 describes the product-series positioning and its upper target range under selected machining conditions. Actual suitability depends on the steel grade, operation, tool diameter, cutting data, holder condition, machine rigidity and coolant strategy. Application details should be reviewed before machining near the upper hardness range.
What operations are suitable for the 4-flute square-end design?
The four-flute square-end geometry supports side milling, shoulder milling, profiling, pocketing, slotting and finishing under suitable cutting conditions. Its flat end supports flat-bottom features and 90° shoulders, while the four-flute configuration provides cutting rigidity for general steel machining.
Why choose four flutes for steel milling?
Four flutes provide more cutting edges per revolution than a two-flute design and support rigid cutting geometry for steel side milling and finishing. The appropriate flute count depends on radial engagement, axial depth, chip evacuation and the required surface finish. Cutting parameters should be matched to the selected tool and operation.
Can this end mill perform full-width slotting and plunge cutting?
Full-width slotting requires suitable cutting parameters and effective chip evacuation, particularly with a four-flute tool. Plunge capability depends on the specific center-cutting geometry, so center-cutting availability and the entry method should be confirmed for the selected size or custom configuration.
Which coating should be selected for steel machining?
AlTiN, TiAlN, TiSiN, AlTiSiN or another application-specific coating may be selected according to the steel grade, hardness, cutting temperature and machining conditions. The coating should be matched with the carbide substrate and edge preparation rather than selected by color alone.
FAQ sur les commandes et la personnalisation
Information for distributors, tooling brands and customers requesting standard or drawing-based configurations.
What standard sizes are available?
The Standard Size Matrix lists 16 reference configurations with cutting diameters from Ø1 to Ø20 mm, flute lengths from 3 to 45 mm, shank diameters from 3 to 20 mm and overall lengths from 50 to 100 mm. Refer to the individual rows for available dimension combinations and confirm availability, helix angle and coating before ordering.
Can non-standard dimensions or geometry be manufactured?
Yes. Selected cutting diameters, flute lengths, overall lengths, shank configurations, helix angles, edge preparation and coatings can be reviewed according to the drawing and machining application. Custom dimensions and tolerances are confirmed before production.
Proposez-vous le marquage OEM et le conditionnement sous marque de distributeur ?
Laser marking, tool codes, custom labels, protective tubes and private-label packaging can be reviewed according to the available marking area, order quantity and confirmed packaging specification.
What information is required for an accurate quotation?
Please provide the workpiece material and hardness, cutting diameter (D), flute length (L1), shank diameter (d), overall length (L), machining operation, axial and radial engagement, coating preference, tolerance requirements, order quantity and any OEM requirements. A tool drawing or component drawing is recommended for custom projects.
