12 best end mill holders

End mill holders are essential components in machining and metalworking industries, particularly in the use of milling machines. They are designed to securely hold end mills, which are cutting tools used for milling operations, such as cutting, shaping, and contouring metals and other materials. Here are some key details about end mill holders:

Purpose: End mill holders serve as adapters or connectors between the milling machine's spindle and the end mill cutting tool. They ensure a secure and precise fit, allowing for accurate machining operations.
Holding Mechanism: End mill holders typically use a collet or set screw mechanism to securely grip the shank of an end mill. The collet style holders provide more precise concentricity and are suitable for high-precision machining.
Accuracy: One of the primary purposes of end mill holders is to maintain accuracy and precision during milling operations. They help reduce runout (eccentricity), which can lead to inaccuracies in the machined workpiece.
Reduction of Vibration: End mill holders can help dampen vibrations generated during milling, leading to improved surface finishes and extended tool life.
Variety of Sizes: End mill holders come in various sizes and types to accommodate different end mill shank diameters. They are typically available in common sizes, including R8, BT, CAT, and more, to fit various milling machine spindles.
Compatibility: It's crucial to choose an end mill holder that is compatible with both the milling machine spindle and the specific end mill being used. Proper compatibility ensures a secure and accurate fit.
Material: End mill holders are commonly made from high-quality materials such as hardened steel or alloy steel. These materials provide durability and strength to withstand the rigors of machining.
Maintenance: Regular maintenance, including cleaning and inspection for wear and damage, is essential to ensure the continued accuracy and reliability of end mill holders.
Coolant and Lubrication: Some end mill holders are designed to allow for the passage of coolant or lubrication to reach the cutting tool, which can improve cutting performance and tool life.
Tool Changes: End mill holders simplify tool changes by providing a quick and secure method for swapping out cutting tools during machining operations.

In summary, end mill holders play a critical role in the precision and accuracy of milling operations. They securely grip end mills, reduce runout, dampen vibrations, and help maintain the quality of machined workpieces. Proper selection and maintenance of end mill holders are essential for achieving high-quality results in metalworking and machining applications.

User questions & answers

Question:	Please confirm that this holder will take a 1 1/2" end mill. The photo is of a smaller holder
Answer:	I do not think this will work for you... This is an R8 shank that is designed to fit in a milling machine. If your router accepts R8 shanks and you want to hold a 1/4 inch cutter then your would want the 3900-0112 holder
Question:	What is the diameter of the shank on the 1/2" or 1-1/2" ones to use on my Kobalt router which only accepts 1/4" shank. Will this work
Answer:	I have the 1/4" tool holder so I am going to presume that the 1" is the same set up. It is threaded in the center for a draw-bar to mount into a R-8 spindle. So yes it has an integrated shank.
Question:	Does it have an integrated shank
Answer:	These are designed with a set screw to hold on the flat but they probably will work on those size end mills. R-8 collets ( HHIP# 3900-0802, 3900-0806) or our ER collet system may be a better choice.
Question:	Hi! Do 1/4 and 1/8 endmills require a Weldon style flat to be used with this adaptor
Answer:	yes we have ,but now is out of stock , and will in stock on Monday !

User questions & answers

Question:	What thread is the drawbar
Answer:	you have to make a new draw bar to use this in a metric machine
Question:	Has anyone used in a harbor freight mini milling machine
Answer:	If your drill press has a 2 morse taper (2MT) spindle this will mate with it.
Question:	does this work in a drill press
Answer:	Yes, Our MT2 and MT3 end mill holders have a 3/8-16" drawbar end thread. The MT4 comes with a 1/2-13 Drawbar end thread.
Question:	What is the thread in the drawbar end? Is it
Answer:	I did not see a guaranteed runout for these. I checkeded mine with a dial indicator and the needle shows no runout on the 1/2 and 3/8. I have not used the others yet.
