Cặp mũi khoan taro GREEN RING M 10 x 1.5, DIN 371, Form B, HSS-E

This TwinBox set was put together for maximum efficiency and reliability.

• Đồng bộ chính xác: The included Mũi khoan xoắn with an 8.5 mm diameter is perfectly matched to the nominal size of the tap (M 10 x 1.5). This ensures that the core hole is optimally prepared for the subsequent cắt ren.
• GREEN RING Quality: The universal GREEN RING symbol stands for a tool that is excellently suited for a wide range of materials with a strength of up to 1000 N/mm².
• For lỗ thông: The Form B tap has an optimized lead that efficiently pushes chips forward and out of the hole—ideal for lỗ thông.
• High-Quality Materials: The tap made of HSSE and the Mũi khoan made of HSS-CO are particularly heat and wear-resistant, ensuring a long service life.

With the TwinBox, you have the two most important tools to cut a perfect thread in just a few steps:

1. Step 1: Drill the core hole. Clamp the included 8.5 mm Mũi khoan xoắn into your machine. Drill the core hole into the workpiece. Pay attention to the correct speed and cooling.
2. Step 2: Cut the thread. Change the tool and securely clamp the tap into the machine. Position the tool exactly in the core hole.
3. Step 3: Start the process. Guide the tap through the hole with a steady feed. Since it is a through hole, the chips are expelled forward.
4. Step 4: Check the thread. Remove the tap and clean the thread. Check the result with a Dưỡng kiểm ren trong to ensure a perfect fit.

Q: Why should I buy a set with a tap and a drill?

A: The biggest advantage is that the tools are perfectly matched. The set contains the exact Mũi khoan xoắn for the core hole of the M 10 x 1.5 thread, which prevents measurement errors and unclean results.

Q: What is the difference between a Form B and a Form C tap?

A: The Form B tap has a short lead (3.5 to 5 threads) and a straight or slightly left-hand spiral flute. It is ideal for lỗ thông because it pushes chips forward and out of the hole. The Form C tap has a spiral that conveys chips upwards and is intended for lỗ bít.

Q: What is the difference between HSS-E and HSS-CO?

A: Both are HSS-based alloys that contain cobalt. HSS-E stands for HSS with a specific cobalt content, typically used for threading tools. HSS-CO is often used for twist drills and also contains cobalt, which increases hardness and heat resistance under high stress.

Q: Why is the Mũi khoan 8.5 mm for an M10x1.5 thread?

A: The rule of thumb for the core hole of metric threads is: Nominal Diameter - Pitch = Core Hole Diameter. In this case, 10 mm - 1.5 mm = 8.5 mm. The Mũi khoan xoắn in the set has exactly this diameter.

Q: What are "malleable cast iron and zinc alloys" relevant for?

A: These are materials often used in manufacturing that are considered "easily machinable." The HSS-E material of the tap and the geometry of the TwinBox tools are optimally matched for working with these materials.
