Angle Grinder Adaptors and Drill Bits

Adapters allow you to mount your bit onto an angle grinder and use it as a modified high-speed drill.  Angle grinders generally run at 10,000 rpm and will make drilling your logs much faster and easier.  Angle grinders are moderately priced and easily available.  Adaptors fit a 5/8″ diameter spindle — generally 41/2″ long and 11 threads per inch. They have been designed to fit most makes and models of angle grinders currently available in North America.

The adapters will fit onto your grinder ‘spindle’ (tighten with appropriate size ‘allen key’) and will take a drill bit on the other end.  both a 12 mm and a 13.5 mm bit  can be used.

FYI:  12mm = .4724 inches  and  13.5 mm = .5118 inches

A  drill bit with a depth stop (such as shown in the picture)  is recommended. It is made specifically for log mushroom cultivation. It augers out the sawdust from the hole and throws it out as it is drilling, leaving a clean hole. A normal wood drill bit  can work but is a secondary choice.  Bits without a depth stop can be fitted with a collar to provide the depth stop, however collars can be difficult to attach and tighten onto the bit.

The following inoculation tools are suitable for larger projects.  The “Stick” inoculator is efficient for inoculating 50 and up to 200 logs.  The “Hand” inoculator will speed up inoculation and is cost effective for inoculating 200 or more logs; to be used with Styrofoam caps to seal insertion holes.  These tools are stainless steel,  high-quality and durable, and will last for many years. They are made in Japan.  We advise you to order directly from the North American distributor – Field and Forest Products Inc.  This will streamline ordering and will keep your costs as low as possible. They are a significant investment and it makes economic sense to have a single ‘broker’ to deal with.  Full pre-payment is required in US$.  Shipment with insurance will be via UPS. Order as early as possible to ensure that you will have your equipment on site when your spawn arrives; allow 3 weeks for delivery.
