Drilling is one of the most fundamental and frequent operations in metalworking. From a precision mounting hole in a small aluminum plate to dozens of bolt holes in a large flange, from single holes to multi-position tapping on batch parts — the rigidity, accuracy, and efficiency of your drilling machine directly determine assembly quality and production cycle times.

As an engineer-driven, integrated manufacturing and trading machine tool provider, Botai Industrial Equipment has built a complete drilling machine product line covering bench, vertical, radial, CNC tapping centers, and CNC vertical drilling machines.

Botai Drilling Machine Naming System and Product Overview

Botai drilling machines follow a unified naming system: B stands for Botai, D for Drilling Machine, and the third letter indicates the type: B for Bench, V for Vertical, R for Radial, T for Tapping Center. Suffix C indicates CNC. Numbers indicate maximum drilling diameter in mm.

Five categories covering the full spectrum from micro precision holes to large heavy-duty drilling:

Bench Drilling Machines (BDB): The Economical Choice for Precision Small-Part Drilling

Bench drilling machines are the most flexible drilling equipment in the workshop, designed for benchtop small-part machining. Botai bench drilling machines come in four models — BDB-13, BDB-20, BDB-25, and BDB-32 — covering drilling capacities from 13mm to 32mm.

Core Features:

• Rigid Cast Iron Body: Minimal spindle runout for accurate drilling
• Wide Speed Range: Suitable for precision drilling of aluminum, plastics, and non-ferrous metals
• Global Voltage Customization: Supports different regional voltage standards
• Reinforced Export Packaging: Strengthened for overseas transportation

Bench drilling machines are widely used in electronics, instruments, home appliance repair, and small hardware batch drilling.

Vertical Drilling Machines (BDV): The Rigid and Stable Universal Drilling Workhorse

Vertical drilling machines are the most common general-purpose drilling equipment in machining shops. Botai vertical drilling machines feature a square column structure with a resin sand cast iron bed, providing high rigidity, stability, and precision. Available in four models — BDV-25A, BDV-32A, BDV-40A, and BDV-50A — based on maximum drilling diameter.

Vertical drilling machines handle drilling, reaming, boring, and tapping operations, making them a reliable choice for general mechanical parts, mold making, and equipment maintenance. The combination of square column structure and resin sand cast iron bed ensures long-term accuracy retention and vibration resistance.

Radial Drilling Machines (BDR): Efficient Multi-Hole Drilling for Large Workpieces

Radial drilling machines are designed for multi-hole machining of large, heavy workpieces. Botai radial drilling machines feature a twin-column structure with hydraulic locking. The spindle head moves horizontally along the radial arm, and the arm rotates around the column, easily covering all hole positions on large workpieces. Available in four models — BDR-40×13/I, BDR-50×16/I, BDR-63×20/I, and BDR-80×25/I.

Core Features:

• High-Strength Cast Iron Bed: Ensures stability during heavy-duty machining
• Full Hydraulic Efficiency: Hydraulic locking and speed change for efficient operation
• Easy-to-Use, Durable Design: Built for long-term, high-intensity use
• Global Voltage Customization + Reinforced Export Wooden Case + Full English Manual: Tailored for overseas customers

Radial drilling machines are widely used in mining machinery, construction machinery, large molds, and steel structures.

CNC Drilling & Tapping Centers (BDT): The Efficiency King for Batch Drilling and Tapping

CNC drilling & tapping centers are the most automated and efficient machines in the drilling category. Botai BDT series includes two models — BDT-50 and BDT-60 — designed specifically for batch drilling and tapping.

Core Features:

• 5.5kW Direct-Drive High-Speed Spindle: Up to 24,000rpm for drilling and tapping in one pass
• 16-Station Servo Tool Magazine: Automatic tool change for continuous multi-process machining
• Taiwan Ball Screws & Guideways + Imported Bearings: High precision, long service life
• Large-Span Bed: High rigidity, lasting accuracy
• Large Travel Design: Outstanding efficiency for batch machining

CNC drilling & tapping centers are ideal for batch production of electronic components, automotive parts, and general mechanical parts requiring high volumes of drilling and tapping. One machine can replace multiple conventional drilling machines, significantly boosting efficiency.

CNC Vertical Drilling Machines (BDV-C): CNC Solutions for Multi-Process Batch Machining

CNC vertical drilling machines add a CNC system to the conventional vertical drilling platform, enabling programmable automatic Z-axis feed for multi-process batch machining of small-to-medium parts. Botai BDV-C series includes two models — BDV-40C and BDV-50C.

Core Features:

• Efficient CNC Machining: User-friendly CNC system, easy to learn
• Programmable Z-Axis Auto Feed: Reduces manual intervention and improves consistency
• Resin Sand High-Strength Cast Iron Bed: Greater rigidity for consistent accuracy in large-diameter drilling
• Reinforced Spindle Structure: Suitable for heavy-load drilling

CNC vertical drilling machines are the upgrade choice from conventional vertical drills, ideal for workshops transitioning from manual to CNC machining while maintaining ease of operation and improving efficiency and consistency.
