Description
Product Overview
This internal-coolant solid carbide drill is designed for CNC hole machining applications requiring coolant delivery close to the cutting zone. The through-coolant channels support cooling, lubrication and chip evacuation during deeper or more demanding drilling operations.
The 2-flute structure provides chip space for material evacuation, while the solid carbide body supports rigidity and dimensional stability. Standard sizes and drawing-based custom dimensions are available for distributors, CNC machining companies, OEM projects and combined cutting-tool orders.
Recommended Drilling Applications
Recommended for CNC drilling applications where coolant delivery, chip evacuation and stable hole machining are important.
Deeper-Hole Drilling
Internal coolant supports heat control and chip evacuation when drilling holes deeper than typical external-coolant applications.
Blind-Hole Machining
Suitable for blind-hole applications requiring controlled chip removal and reduced chip accumulation inside the hole.
Through-Hole Machining
Supports stable through-hole drilling where controlled breakthrough and consistent coolant supply are required.
Batch CNC Production
Suitable for repeated hole machining when consistent tool dimensions, coolant delivery and repeatable supply are needed.
Application Confirmation Is Recommended
Drill diameter, hole depth, depth-to-diameter ratio, workpiece material, machine rigidity, spindle runout, coolant pressure and toolholding condition should be reviewed before selecting the final drill specification.
Tool Structure and Drilling Performance
The solid carbide body, internal coolant channels and 2-flute structure work together to support stable hole machining and chip evacuation.
Solid Carbide Construction
The solid carbide body supports tool rigidity, dimensional stability and repeatable cutting geometry during CNC drilling.
Internal Coolant Channels
Coolant channels deliver coolant closer to the drill point and cutting edges, supporting cooling and lubrication at the cutting zone.
Improved Chip Evacuation
Through-coolant delivery helps move chips through the flutes and reduce chip congestion during deeper-hole drilling.
2-Flute Chip Space
The 2-flute configuration provides chip space while maintaining the drill structure required for stable hole machining.
Application-Specific Coating
Coating can be selected according to the workpiece material, cutting heat, wear condition and required production volume.
Custom Dimension Support
Diameter, cutting length, overall length, shank size and drilling depth can be reviewed for drawing-based production.
