China Suppliers Factory Hand Drill to Polishing Angle Grinder Connection Conversion Rod for Electric Drills
Material and Craftsmanship
The main body is made of 45 # high-quality carbon steel, which is precision forged and subjected to high-frequency quenching and tempering double heat treatment. It has high hardness and strong torsional resistance, and can withstand high-speed torque of ten thousand revolutions per minute for hand drills. The black version is treated with blackening and rust prevention, while the silver version is treated with galvanizing and passivation. It is wear-resistant and corrosion-resistant, making it easy to cope with complex working conditions such as dust and humidity on construction sites. The precision machined three spoke handle and standard M10/M14 external thread have a coaxiality error of ≤ 0.02mm, zero eccentricity and no shaking during high-speed operation, ensuring operational accuracy and tool safety.
Core Strengths
1. Exclusive Design of Sanling Handle
The triangular handle structure perfectly clamps the three groove chuck of the electric drill, which improves the anti slip performance by three times compared to the round handle. It never slips during high-speed rotation, completely solving the problem of traditional connecting rod slipping and shaking, and fully pulling the locking force.
2. Full Specification Adaptation
Covering long and short styles, positive and negative threads, and different lengths, it is compatible with the full range of grinding discs, cutting discs, and polishing wheels of the 100/125 angle grinder, and is compatible with the vast majority of three slot chuck hand drills.
3. Zero Threshold Modification
No need for professional tools. Install the three spoke handle into the drill chuck and lock it, and use a pressure plate to fix the grinding disc. The modification can be completed in 1 minute without the need to purchase an additional angle grinder, greatly reducing tool costs.
4. Stable and Durable Structure
The middle limit platform+integrated hexagonal locking structure ensures even force distribution, firm installation, and does not deform or slide during heavy-duty operations. Its service life far exceeds that of ordinary connecting rods.
Main Purpose
Widely used in household DIY, decoration and construction, automotive beauty, hardware processing and other scenarios: can be converted into a lightweight angle grinder to complete metal cutting, stone polishing, rust removal and deburring; Convert into a polishing machine to achieve car paint waxing, furniture polishing, and hardware mirror treatment; The combination of long and short styles allows for deep operation in narrow spaces such as cabinets and pipelines. It is an essential modification accessory for users of three slot chuck electric drills, greatly improving tool flexibility and operational efficiency.
Frequently Asked Questions
What material is the connection rod made of?
The main body is constructed from 45# high-quality carbon steel, precision forged and double heat-treated through high-frequency quenching and tempering for high hardness and strong torsional resistance.
What are the benefits of the exclusive Sanling handle design?
The triangular structure of the Sanling handle perfectly clamps the three-groove chuck of your electric drill, improving anti-slip performance by three times compared to traditional round handles. It prevents slipping and shaking during high-speed rotation.
Is it compatible with my existing angle grinder discs?
Yes, it is fully compatible with the grinding discs, cutting discs, and polishing wheels of 100/125 angle grinders. It supports standard M10/M14 external threads and fits the vast majority of three-slot chuck hand drills.
How long does the installation take?
The modification features a zero-threshold design. You can insert the three-spoke handle into the drill chuck, lock it, and fix the grinding disc with a pressure plate in just 1 minute without any professional tools.
Does the adapter shake at high speeds?
No, the precision machined three-spoke handle keeps the coaxiality error at ≤ 0.02mm, ensuring zero eccentricity and no shaking even when operating under high-speed rotation.
What are the differences between the black and silver versions?
The black version is treated with blackening and rust prevention, while the silver version is treated with galvanizing and passivation. Both versions are highly wear-resistant and corrosion-resistant.
