Converting rotary hammers into high-torque socket drivers requires the Tolsen 77865 set. This 3-piece kit adapts 1/4, 3/8, and 1/2 inch square drives to standard SDS-Plus shanks. Users switch from drilling masonry to driving heavy bolts without changing power tools.
Key Features
- 40Cr Alloy Steel: Hardened 40Cr steel construction withstands high-torque impact forces. Bits won't snap under load.
- Spring-Loaded Ball Bearing: Integrated steel balls lock sockets onto the 10mm shanks. Sockets stay attached despite road dust.
- Universal SDS-Plus: Standard 10mm diameter shanks fit most rotary hammer drills. Connects impact sockets to hammer drills.
- Sandblasted Finish: Matte surface treatment prevents corrosion and improves grip. Resists rust during high humidity.
- Portable 132g Weight: Three-piece set weighing 132g with 65-75mm total length. Fits inside tool vest pockets.
Frequently Asked Questions
Can I use SDS plus bits in a regular drill?
No, the 10mm SDS-Plus shank requires a specific grooved chuck found in rotary hammers. Standard 3-jaw chucks cannot grip the indented shank properly.
What is 40Cr steel used for?
This alloy provides high tensile strength and toughness for impact-heavy components. It reduces the risk of metal fatigue in high-torque drill bit adaptors.
Does this SDS Plus to square socket adapter fit all drills?
The adapter fits any rotary hammer equipped with an SDS-Plus chuck. It will not lock into standard hexagonal or round-shank drill drivers.
