Heavy Duty Pneumatic Air Screwdriver Impact Screw Driver Woodworking Tools

When a self-tapping screw stalls halfway into hardwood, the operator usually blames the bit or the screw. More often the tool lacks the twist force for that screw length. Running a 60N.M driver on 85mm screws burns time and strips heads. Matching the driver to the screw range removes that daily failure point before it starts.

The 5H, 8H, 8HL and 10H are pneumatic air screwdrivers with metal and plastic bodies in blue. All four run at 6kg/cm working pressure. Free speed is 9000rpm on the 5H and 8000rpm on the 8H, 8HL and 10H. Twist force is 60N.M, 170N.M, 170N.M and 195N.M respectively.

Check the air line holds 6kg/cm before mounting. The 5H takes self-tapping screws below 60mm and screws and nuts below M8. The 8H and 8HL take screws below 85mm and nuts below M10mm. The 10H takes screws below 110mm and nuts below M10mm. Correct pressure keeps free speed and twist force at the stated figures.

Each screwdriver is individually packed. Send your model number, the screw lengths and nut sizes you run, and your air line pressure with the enquiry. That lets us confirm the 5H, 8H, 8HL or 10H matches your work before you order. Delivery place is Foshan, Guangdong, China.

What the specification fixes, and what it leaves to the machine:

• Screw length capacity — The 5H drives self-tapping screws below 60mm, while the 8H and 8HL cover screws below 85mm and the 10H covers screws below 110mm.
• Nut size range — The 5H handles screws and nuts below M8; the 8H, 8HL and 10H handle screws and nuts below M10mm.
• Twist force by model — Twist force is 60N.M on the 5H, 170N.M on the 8H and 8HL, and 195N.M on the 10H.
• Free speed difference — The 5H runs at 9000rpm free speed; the 8H, 8HL and 10H run at 8000rpm free speed.
• Working pressure setting — All four models run at 6kg/cm working pressure, so one air line setting covers the range.
• Body material — Metal and plastic construction in blue, with the metal carrying the impact load and the plastic forming the grip.
• Model selection check — Match screw length and nut size to the model table before ordering; the 10H covers the longest screws at below 110mm.
• Packing for stock — Each screwdriver is individually packed, so units can go straight to a shelf or tool crib without repacking.
• Impact use on assembly — The 8H and 10H are impact screwdrivers for self-tapping screws and nuts in woodworking assembly work.

What changes on the shop floor once the unit is in place:

• Match the driver to the screw. Choosing between 60N.M and 195N.M twist force by screw length stops the stripped heads and stalled drives that come from using one driver on every job.
• One pressure setting across four models. Every model runs at 6kg/cm, so a shop running several screwdrivers does not need separate regulator settings for each one on the line.
• Cover long screws with the 10H. At 195N.M and screws below 110mm, the 10H takes the longest self-tapping work in the range without stepping up to a heavier tool.
• Pick speed for the job. The 5H free speed of 9000rpm suits shorter screws, while 8000rpm on the 8H, 8HL and 10H gives controlled drive on longer screws and M10mm nuts.
• Narrow the choice by nut size. The M8 limit on the 5H and M10mm limit on the other three let a buyer settle the model from the nut sizes already on the bench.
• Individual packing for tool cribs. Each unit arrives individually packed, which keeps models separate in stores and avoids mixed boxes when several screwdrivers are issued.
• Confirm before you commit. Send screw lengths, nut sizes and line pressure with your enquiry, and the model number can be checked against the capacity figures before ordering.

The 8H or 8HL. Both are rated for self-tapping screws below 85mm and screws and nuts below M10mm, with 170N.M twist force and 8000rpm free speed.

No. The 5H is rated for screws and nuts below M8, so M10 work needs the 8H, 8HL or 10H, which are rated below M10mm.

6kg/cm. All four models, 5H, 8H, 8HL and 10H, are rated at 6kg/cm working pressure.

The capacity and output figures are the same: both take screws below 85mm and nuts below M10mm, with 170N.M twist force and 8000rpm free speed. The model codes differ.

Check the length against 110mm. The 10H is rated for self-tapping screws below 110mm and screws and nuts below M10mm, with 195N.M twist force.

Metal and plastic, in blue. The metal carries the impact load and the plastic forms the grip.

Individually packed, one unit per pack.

The model number you are considering, your screw lengths, your nut sizes and your air line pressure. That lets the model be checked against the capacity figures before you order.
