READ INSTRUCTIONS
• Thoroughly read and understand these product instructions before using
this tool. Failure to follow all warnings can result in tool damage or serious
physical injury.
• Keep these product instructions for future reference.
HEALTH HAZARD!
• Dust and fine particles are generated while grinding which can contain
hazardous or toxic substances. Breathing this dust can cause many
serious respiratory health conditions. Always use NIOSH approved
respiratory protection while using this tool.
• During the grinding of 2% thoriated tungsten electrodes, radioactive dust
is created, posing the potential hazard of internal radiation exposure by
inhalation or ingestion unless care is taken to control the dust. If grinding
2% thoriated tungsten, properly control and collect the dust; have an
adequate ventilation system at the grinding station; and follow the
manufacturer’s warnings, instructions, and MSDS.
EYE INJURY HAZARD!
• Rapidly rotating surfaces can eject metal particles and dust at high velocity.
Always wear ANSI approved eye protection when operating this tool.
HEARING DAMAGE HAZARD!
• The Eastwood Tungsten Grinder emits elevated sound levels while operating.
Use ANSI approved ear protection when operating this tool.
INJURY HAZARD!
• DO NOT attempt to operate the Tungsten Grinder without the Grinding Guide
in place as severe cuts or finger removal can occur.

INJURY HAZARD!
• This tool has high-speed, highly abrasive cutting surfaces which can quickly
cause severe injury. Keep fingers and hands away from moving parts when
operating. Wear thick, well-fitting work gloves and keep loose clothing,
sleeves, cords, jewelry and hair away from moving parts.
• Always turn off Power Switch and disconnect tool from electrical supply
when breaking off tungsten tips to prevent pieces of tungsten from falling
into and being ejected from cutting area and potential severe injury.
• DO NOT exert excess force on Tungsten while grinding as it can break and
suddenly eject sharp pieces at high velocity.
• Always turn off Power Switch and disconnect tool from electrical supply
when flipping or changing Grinding Wheels to prevent accidental tool starting
and potential severe injury.
• This tool could eject a trail of sparks at high speed which can ignite
flammable materials or injure others nearby. Do not operate near flammable
materials and keep all persons and pets away from the work area.
• Always hold the tungsten with open fingers while grinding as it can
suddenly kick back causing hand puncture wounds. Wear thick,
well-fitting work gloves.
• Always make sure the tool is securely held to avoid sudden movements
which could result in injury.
• Frequently inspect Grinding Wheel and tool condition. If cracks or chips
develop, discontinue tool use immediately and replace damaged Wheel.
ONLY USE replacement Wheels rated at 40,000 RPM or greater. Severe
injury can result in the event of Grinding Wheel failure.
VIBRATION INJURY HAZARD!
• This tool will vibrate during use! Repeated exposure to vibration may
cause physical injury.
• Use care not to cover motor cooling slots with a gloved hand while
in operation to avoid overheating.

GENERAL SAFETY
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets
will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying
power tools with your finger on the switch or plugging in power tools that have the switch on
invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of these devices can reduce dust-related hazards.

GENERAL SAFETY
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The correct power
tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before
making any adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the
hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the power tools operation. If damaged, have the power
tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the
manner intended for the particular type of power tool, taking into account the working conditions and
the work to be performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.

one at 22.5° to direct the tungsten at
the preferred angle against the Diamond
Grinding Wheel (FIG 1).
- Two 3/32” slots; one angled at 10° and
one at 22.5° to direct the tungsten to
the preferred angle against the Diamond
Grinding Wheel (FIG 1).
- Two notches (1/16” & 3/32”) cut into the
top, outside edge of the Grinding Head.
These slots are designed to grip the

OPERATION
• Move the On-Off Switch located on
the underside of the Housing to the
“OFF” position.
• Plug the power cord into a 120VAC,
60HZ outlet.
• While holding the Eastwood Tungsten
Grinder securely, move the On-Off
Switch to the “On” position.

position (FIG 2). This is the ideal
speed setting for tungsten grinding.
• To begin grinding, allow several seconds for the motor to reach full speed then gently place the
tungsten into the proper width slot (FIG 3).
• Slowly and steadily allow the tungsten to contact the face of the Diamond Grinding Wheel while
rolling the tungsten to create a sharpened tip. DO NOT force the tungsten but allow the abrasive
of the Diamond Grinding Wheel to do the work.
• When the grinding is complete, withdraw the tungsten and move the On-Off Switch to the
“OFF” position.
