Description
Product Overview
This custom long-reach solid carbide drill is designed for extended-reach and deeper-hole CNC machining applications where a standard-length drill cannot access the required feature. The extended cutting and overall length can be developed according to the hole depth, component geometry and machine conditions.
The solid carbide body supports tool rigidity and dimensional stability, while the spiral-flute structure provides a path for chip evacuation. Tool diameter, cutting length, overall length, shank size, point geometry, coating and coolant configuration can be reviewed according to drawings and application requirements.
Recommended Drilling Applications
Recommended for components requiring increased drilling reach, customized hole depth or access beyond the capability of standard-length carbide drills.
Extended-Reach Drilling
Suitable for recessed holes and difficult-to-access features requiring additional tool length or overhang.
Deeper-Hole Machining
Can be developed for hole depths beyond standard drill lengths after reviewing chip evacuation and coolant conditions.
Recessed Component Features
Suitable for holes located behind shoulders, inside cavities or within components where tool access is restricted.
Drawing-Based Projects
Available for non-standard hole features requiring customized diameter, reach, shank dimensions or point geometry.
Long-Reach Drilling Requires Application Review
Hole diameter, drilling depth, tool overhang, workpiece material, machine rigidity, spindle runout, coolant supply and chip-evacuation conditions should be reviewed before confirming the final drill design.
Tool Structure and Drilling Performance
The solid carbide body, extended-length structure, spiral flutes and application-specific geometry work together to support customized drilling operations.
Solid Carbide Construction
The solid carbide body supports cutting-edge stability, tool rigidity and dimensional consistency during CNC drilling.
Extended-Length Design
Cutting length, reach and overall length can be increased according to the required hole position and drilling depth.
Spiral-Flute Chip Path
The spiral-flute structure provides a path for chip evacuation during extended-reach and deeper-hole machining.
Application-Specific Coating
Coating can be selected according to the workpiece material, cutting heat, abrasive wear and production requirements.
Custom Point Geometry
Point angle, cutting-edge preparation and entry geometry can be reviewed according to the material and hole feature.
Custom Coolant Configuration
External or internal coolant options can be reviewed according to the tool diameter, drilling depth and machine coolant system.
Standard and Custom Long-Reach Drill Sizes
Dimensions can be developed according to the required hole diameter, drilling depth, tool reach, machine clearance and component geometry.
