SF Single-Edge Drill Bit IntroductionSF Series Single-Edge Drill Introduction
The image on the right shows the typical appearance of the Chuan Run (川润) SF series multifunctional single-edge drill, which is a representative image of this series of tools.
Also known as multifunctional drilling and boring integrated drill
Material: The tool body is made of 42CrMo, ensuring high strength and durability; the cutting part uses indexable carbide inserts (such as the QCMT series, offering various coating options), combining economy and excellent performance.
The SF series single-edge drill is a composite machining tool that integrates drilling, end face turning, outer diameter turning, and boring functions. Its processing diameter covers
Φ8mm – Φ25mm (such as SF-8R-2.5D-C20 to SF-25R-2.5D-C32, more options can be consulted based on demand).
Created on 09.02VMD & VMC Large Drill IntroductionThe right image shows the typical appearance of the VMD Large-Diameter Deep-Hole Drill, which is the representative image of this series of tools.
Material: Mainly using the Chuan Run brand, the drill rod material is 42CRMO, while the blade and center drill are made of hard alloy (such as TiN-H coating), with a sturdy and durable structure.
The VMD large drill is a large diameter deep hole machining tool with a replaceable and modular design, commonly used for machining large holes with diameters greater than Φ45–Φ180 mm (for larger diameter needs, please consult), and can complete high-efficiency drilling tasks with a depth of 3–10 times the diameter in one processing.
Its core advantages lie in
Created on 08.11Modular Drill -HLD Series IntroductionHLD Replaceable Modular Drill
Because the tip of the drill resembles a crown, it is also known as the Crown Drill.
HLD Crown Drill Bits are suitable for
a diameter range of 12.5-40 mm (4921-1.5748 inches) and
a maximum diameter of 12 times the drilling application.
HLD can achieve the highest feed rate, resulting in the highest productivity.
Efficiency and precision are much higher than that of U-drills.
The blade holder has four large contact surfaces, providing maximum stability even under challenging conditions such as stacked plates, cross holes, and inclined exits.
The central locking screw mechanism ensures that the blade is securely clamped, ensuring processing safety and extending the service life of the drill body and blade. The tip geometry designed for specific materials allows for flexibility.

Created on 05.07Installation of oil channel tool holderInstallation and adjustment steps of oil circuit tool holder (external cooling to internal cooling tool holder) 1. First confirm the distance from the center of the oil circuit tool holder (external cooling to internal cooling tool holder) to the positioning position, BT40=65mm; BT50=80mm, please see the specification table (B) and compare it with the distance from the center of the machine tool spindle to the fixed seat. If the distance does not match, the customer adjusts the position of the water inlet hole of the fixing seat by himself and then installs it (the dust cover screw holes on the fixing block and the end face of the machine tool spindle match). 2. Oil circuit tool holder (external cooling to internal cooling tool holder) a. Install the fixing block on the end face of the machine tool and connect the water inlet pipe to the positioning block. b. Installation of oil-circuit toolholder (external cooling to internal cooling toolholder): First loosen the M6 thread on the positioning key so that the positioning column can move up and down freely (there is a spring under the positioning column), and then install the positioning ring on the
Created on 03.28Answers to common questions about mold manufacturingWhat are the most important and decisive factors in selecting tool steel? Forming method - There are two basic material types to choose from. A) Hot working tool steels, which can withstand the relatively high temperatures of die casting, forging and extrusion. B) Cold working tool steels, which are used for blanking and shearing, cold forming, cold extrusion, cold forging and powder pressing. Plastics - Some plastics produce corrosive by-products, such as PVC plastic. Factors such as condensation caused by long downtime, corrosive gases, acids, cooling/heating, water or storage conditions can also cause corrosion. In these cases, stainless steel tool steel is recommended. Tool size - Large size tools often use pre-hardened steel. Through-hardened steel is often used for small size tools. Tool

Spade drill diameter range: ø9.5mm~~ø114mm Effective length: 50/70/100/150/200/250/300/350/400/450/500mm The blade design is suitable for deep hole processing. The spiral blade design and central water outlet (internal cooling) optimize the chip removal function. A single tool holder can be equipped with a variety of blades, which is economical and affordable. * The tool bar length can be customized according to processing needs. The range of equipment used is wide (can be used for radial drills, vertical drills, horizontal beds, machining centers and other equipment), and the rigidity requirements of the equipment are not high. The integral cutter head can be accurately centered, the cutter head has chip grooves and chip breakers, and can process deep holes. Spade drills are generally used for medium-speed processing between U-drilling and ordinary drilling. The general blade is high-speed
