Description

EXTERNAL COOLANT · SOLID CARBIDE · 2 FLUTES

Product Overview

This external-coolant solid carbide drill is designed for
general CNC hole machining under external coolant or lubrication
conditions. The 2-flute structure provides chip space for
material evacuation, while the solid carbide body supports
rigidity and dimensional stability during drilling.

Tool diameter, cutting length, overall length, shank dimensions,
coating and point geometry can be selected according to the
workpiece material, hole feature and production requirements.
Standard sizes and drawing-based custom tools are available for
distributors, machining companies and OEM customers.

Recommended Drilling Applications

Recommended for standard CNC drilling applications where
stable toolholding, external coolant supply and controlled
chip evacuation are available.

01

General Hole Drilling

Suitable for standard holes in plates, blocks,
housings and general CNC-machined components.

02

Through-Hole Machining

Supports through-hole drilling where chip evacuation
and controlled breakthrough are required.

03

Shallow Blind Holes

Can be selected for blind-hole machining when hole
depth, chip removal and coolant conditions are suitable.

04

Batch CNC Production

Suitable for repeated hole machining requiring
consistent tool dimensions and repeatable supply.

Application Confirmation Is Recommended

Drill diameter, hole depth, depth-to-diameter ratio,
workpiece material, machine rigidity, spindle runout,
external coolant direction and toolholding condition
should be reviewed before selecting the final drill.

Tool Structure and Drilling Performance

The solid carbide construction, 2-flute geometry and
material-specific coating support stable CNC hole machining
under suitable external-coolant conditions.

01

Solid Carbide Construction

The solid carbide body supports tool rigidity,
cutting-edge stability and dimensional consistency
during CNC drilling.

02

2-Flute Chip Space

The 2-flute configuration provides space for chip
formation and evacuation from the drilled hole.

03

External-Coolant Application

External coolant or lubrication can support cutting-zone
cooling and chip movement in standard drilling conditions.

04

Application-Specific Coating

Coating can be selected according to the workpiece
material, cutting heat, wear condition and required
production volume.

05

Point Geometry Options

Standard or customized point geometry can be reviewed
according to the material, hole feature and entry condition.

06

Custom Dimension Support

Diameter, cutting length, overall length and shank
dimensions can be produced according to confirmed
specifications or customer drawings.
